12 daysGCN: Set 'UI_TARGET' for 'TARGET_EXCEPT_UNWIND_INFO' [PR94282, PR113331]Thomas Schwinge1-0/+22
In commit 7f1989249e25af6fc0f124452efa24b3796b767a "[gcn] Set 'UI_NONE' for 'TARGET_EXCEPT_UNWIND_INFO' [PR94282]", we've copied the 'UI_NONE' idea from nvptx to GCN. I understand the intention of using 'UI_NONE' like this, and it happens to work in a lot of cases, but there are ICEs elsewhere: code paths where we run into 'internal compiler error: in get_personality_function, at expr.cc:13512': 13494 /* Extracts the personality function of DECL and returns the corresponding 13495 libfunc. */ 13496 13497 rtx 13498 get_personality_function (tree decl) 13499 { 13500 tree personality = DECL_FUNCTION_PERSONALITY (decl); 13501 enum eh_personality_kind pk; 13502 13503 pk = function_needs_eh_personality (DECL_STRUCT_FUNCTION (decl)); 13504 if (pk == eh_personality_none) 13505 return NULL; 13506 13507 if (!personality 13508 && pk == eh_personality_any) 13509 personality = lang_hooks.eh_personality (); 13510 13511 if (pk == eh_personality_lang) 13512 gcc_assert (personality != NULL_TREE); 13513 13514 return XEXP (DECL_RTL (personality), 0); 13515 } ..., where 'lang_hooks.eh_personality ()' ends up calling 'gcc/expr.cc:build_personality_function', and we 'return NULL;' for 'UI_NONE': 13448 /* Build a decl for a personality function given a language prefix. */ 13449 13450 tree 13451 build_personality_function (const char *lang) 13452 { 13453 const char *unwind_and_version; 13454 tree decl, type; 13455 char *name; 13456 13457 switch (targetm_common.except_unwind_info (&global_options)) 13458 { 13459 case UI_NONE: 13460 return NULL; [...] (Comparing to nvptx' current use of 'UI_NONE', this problem (ICEs mentioned above) is way more prevalent for GCN.) The GCC internals documentation indeed states, 'gcc/doc/tm.texi': @deftypefn {Common Target Hook} {enum unwind_info_type} TARGET_EXCEPT_UNWIND_INFO (struct gcc_options *@var{opts}) This hook defines the mechanism that will be used for exception handling by the target. If the target has ABI specified unwind tables, the hook should return @code{UI_TARGET}. If the target is to use the @code{setjmp}/@code{longjmp}-based exception handling scheme, the hook should return @code{UI_SJLJ}. If the target supports DWARF 2 frame unwind information, the hook should return @code{UI_DWARF2}. A target may, if exceptions are disabled, choose to return @code{UI_NONE}. This may end up simplifying other parts of target-specific code. [...] Here, note: "if exceptions are disabled" (meaning: '-fno-exceptions' etc.) may "return @code{UI_NONE}". That's what other back ends do with code like: /* For simplicity elsewhere in this file, indicate that all unwind info is disabled if we're not emitting unwind tables. */ if (!opts->x_flag_exceptions && !opts->x_flag_unwind_tables) return UI_NONE; else return UI_TARGET; The corresponding "simplifying other parts of target-specific code"/ "simplicity elsewhere" would then be the early returns from 'TARGET_ASM_UNWIND_EMIT', 'ARM_OUTPUT_FN_UNWIND', etc. for 'TARGET_EXCEPT_UNWIND_INFO != UI_TARGET' (that is, for 'UI_NONE'). From the documentation (and implementation), however, it does *not* follow that if a target doesn't implement support for exception handling, it may just set 'UI_NONE' for 'TARGET_EXCEPT_UNWIND_INFO'. Therefore, switch to 'UI_TARGET', allocating a "fake" 'exception_section'. With that, all these 'internal compiler error: in get_personality_function' test cases turn into PASS, or UNSUPPORTED ('exception handling not supported'), or re-classify into a few other, already known issues. And, this change also happens to resolve the class of errors identified in GCC PR113331 "AMDGCN: Compilation failure due to duplicate .LEHB<n>/.LEHE<n> symbols". (In case that use of 'UI_NONE' like originally intended really makes sense, and is preferable over this 'UI_TARGET' solution, then more work will be necessary for implementing the missing parts, where 'UI_NONE' currently isn't handled.)

2025-02-10[gcn] mkoffload.cc: Print fatal error if -march has no multilib but generic hasTobias Burnus1-7/+94
Assume that a distro has configured, e.g., a gfx9-generic multilib but not for gfx902. In that case, mkoffload would fail to link with "error: incompatible mach". With this commit, an error is printed suggesting to try the associated generic architecture instead. The behavior is unchanged if there is a multilib available for the specific ISA or when there is also no multilib for the generic ICA. Note: The build of generic multilibs are currently not enabled by default; they also require the linker/assembler of LLVM 19 or newer and, in particular, for the execution a future ROCm release. (The next one? In any case, 6.3.2 does not support generic ISAs, yet.) gcc/ChangeLog: * config/gcn/mkoffload.cc (enum elf_arch_code): Add EF_AMDGPU_MACH_AMDGCN_NONE. (elf_arch): Use enum elf_arch_code as type. (tool_cleanup): Silence warning by removing tailing '.' from error. (get_arch_name): Return enum elf_arch_code. (check_for_missing_lib): New; print fatal error if the multilib is not available but it is for the associate generic ISA. (main): Call it.
2025-02-08GCN, nvptx: 'sorry, unimplemented: exception handling not supported'Thomas Schwinge1-0/+7
For GCN, this avoids ICEs further down the compilation pipeline. For nvptx, there's effectively no change: in presence of exception handling constructs, instead of 'sorry, unimplemented: target cannot support nonlocal goto', we now emit 'sorry, unimplemented: exception handling not supported'. Additionally, turn test cases into UNSUPPORTED if running into 'sorry, unimplemented: exception handling not supported'. gcc/ * config/gcn/gcn.md (exception_receiver): 'define_expand'. * config/nvptx/nvptx.md (exception_receiver): Likewise. gcc/testsuite/ * lib/gcc-dg.exp (gcc-dg-prune): Turn 'sorry, unimplemented: exception handling not supported' into UNSUPPORTED. * gcc.dg/pr104464.c: Remove GCN XFAIL. libstdc++-v3/ * testsuite/lib/prune.exp (libstdc++-dg-prune): Turn 'sorry, unimplemented: exception handling not supported' into UNSUPPORTED.
2025-02-07[gcn] Fix the output amdhsa.versionTobias Burnus2-7/+14
The amdhsa.version depends on the code object version; while V3 had 1.0, V4 has 1.1 and V5 (and V6) have 1.2. GCC used 1.0 but generated since a while either V4 or, with -march=gfx...-generic, V6. Now it uses the proper version again. gcc/ChangeLog: * config/gcn/gcn.cc (gcn_hsa_declare_function_name): Update 'amdhsa.version' output to match used code version. * config/gcn/gen-gcn-device-macros.awk: Add a comment to crosslink.
2025-02-07[gcn] Add gfx9-generic and generic-associated gfx*Tobias Burnus2-11/+236
This patch adds gfx9-generic, completing the gfx*-generic support. It also adds all gfx* devices that are part of any of the gfx*-generic, i.e. gfx902, gfx904, gfx909, gfx1031, gfx1032, gfx1033, gfx1034, gfx1035, gfx1101, gfx1102, gfx1150, gfx1151, gfx1152, and gfx1153. gcc/ChangeLog: * config/gcn/gcn-devices.def (GCN_DEVICE): Add gfx9-generic, gfx902, gfx904, gfx909, gfx1031, gfx1032, gfx1033, gfx1034, gfx1035, gfx1101, gfx1102, gfx1150, gfx1151, gfx1152, and gfx1153.

2025-02-07[gcn] Fix gfx906's sramecc settingTobias Burnus2-2/+3
When compiling with -g, mkoffload.cc creates a device object file itself; however, in order that the linker dos not complain, the ELF flags must match what the compiler / linker does. For gfx906, the assembler defaults to sramecc = any, but gcn-devices.def contained unsupported, which is not the same - causing link errors. That's a regression caused by commit r15-4540-ga6b26e5ea09779 - which can be best seen by looking at the changes to mkoffload.cc. Additionally, this commit adds '...' to the GCN_DEVICE #define in gcn.cc to make it agnostic to the addition of fields. gcc/ChangeLog: * config/gcn/gcn-devices.def (GCN_DEVICE): Change sramecc for gfx906 to 'any'. * config/gcn/gcn.cc (GCN_DEVICE): Add tailing ... to #define.

2024-12-11middle-end: Pass stmt_vec_info to TARGET_SIMD_CLONE_USABLE [PR96342]Andre Vieira1-1/+2
This patch adds stmt_vec_info to TARGET_SIMD_CLONE_USABLE to make sure the target can reject a simd_clone based on the vector mode it is using. This is needed because for VLS SVE vectorization the vectorizer accepts Advanced SIMD simd clones when vectorizing using SVE types because the simdlens might match. This will cause type errors later on. Other targets do not currently need to use this argument. gcc/ChangeLog: PR target/96342 * target.def (TARGET_SIMD_CLONE_USABLE): Add argument. * tree-vect-stmts.cc (vectorizable_simd_clone_call): Pass stmt_info to call TARGET_SIMD_CLONE_USABLE. * config/aarch64/aarch64.cc (aarch64_simd_clone_usable): Add argument and use it to reject the use of SVE simd clones with Advanced SIMD modes. * config/gcn/gcn.cc (gcn_simd_clone_usable): Add unused argument. * config/i386/i386.cc (ix86_simd_clone_usable): Likewise. * doc/tm.texi: Regenerate Co-authored-by: Victor Do Nascimento <victor.donascimento@arm.com> Co-authored-by: Tamar Christina <tamar.christina@arm.com>

2024-12-06diagnostics: UX: add doc URLs for attributes (v2)David Malcolm1-0/+3
This is v2 of the patch; v1 was here: https://gcc.gnu.org/pipermail/gcc-patches/2024-June/655541.html Changed in v2: * added a new TARGET_DOCUMENTATION_NAME hook for figuring out which documentation URL to use when there are multiple per-target docs, such as for __attribute__((interrupt)); implemented this for all targets that have target-specific attributes * moved attribute_urlifier and its support code to a new gcc-attribute-urlifier.cc since it needs to use targetm for the above; gcc-urlifier.o is used by the driver. * fixed extend.texi so that some attributes that failed to appear in attr-urls.def now do so (affected nvptx "kernel" and "shared" attrs) * regenerated attr-urls.def for the above fix, and bringing in attributes added since v1 of the patch In r14-5118-gc5db4d8ba5f3de I added a mechanism to automatically add documentation URLs to quoted strings in diagnostics. In r14-6920-g9e49746da303b8 I added a mechanism to generate URLs for mentions of command-line options in quoted strings in diagnostics. This patch does a similar thing for attributes. It adds a new Python 3 script to scrape the generated HTML looking for documentation of attributes, and uses this to (re)generate a new gcc/attr-urls.def file. Running "make regenerate-attr-urls" after rebuilding the HTML docs will regenerate gcc/attr-urls.def in the source directory. The patch uses this to optionally add doc URLs for attributes in any diagnostic emitted during the lifetime of a auto_urlify_attributes instance, and adds such instances everywhere that a diagnostic refers to a diagnostic within quotes (based on grepping the source tree for references to attributes in strings and in code). For example, given: $ ./xgcc -B. -S ../../src/gcc/testsuite/gcc.dg/attr-access-2.c ../../src/gcc/testsuite/gcc.dg/attr-access-2.c:14:16: warning: attribute ‘access(read_write, 2, 3)’ positional argument 2 conflicts with previous designation by argument 1 [-Wattributes] with this patch the quoted text `access(read_write, 2, 3)' automatically gains the URL for our docs for "access": https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#index-access-function-attribute in a sufficiently modern terminal. Like r14-6920-g9e49746da303b8 this avoids the Makefile target depending on the generated HTML, since a missing URL is a minor problem, whereas requiring all users to build HTML docs seems more involved. Doing so also avoids Python 3 as a build requirement for everyone, but instead just for developers addding attributes. Like the options, we could add a CI test for this. The patch gathers both general and target-specific attributes. For example, the function attribute "interrupt" has 19 URLs within our docs: one common, and 18 target-specific ones. The patch adds a new target hook used when selecting the most appropriate one. Signed-off-by: David Malcolm <dmalcolm@redhat.com> gcc/ChangeLog: * Makefile.in (OBJS): Add -attribute-urlifier.o.

2024-11-22build: Remove INCLUDE_MEMORY [PR117737]Andrew Pinski1-1/+0
Since diagnostic.h is included in over half of the sources, requiring to `#define INCLUDE_MEMORY` does not make sense. Instead lets unconditionally include memory in system.h.

2024-11-19amdgcn: Fix build failure (PR117657)Andrew Stubbs1-3/+4
The last patch did the right thing to the wrong parameter, which caused a build failure in Newlib. This patch fixes it. gcc/ChangeLog: PR target/117657 * config/gcn/gcn-valu.md (mask_gather_load<mode><vnsi>): Fix bug in maskload else patch.
2024-11-18gcn: Add else operand to masked loads.Robin Dapp2-12/+13
This patch adds an undefined else operand to the masked loads. gcc/ChangeLog: * config/gcn/predicates.md (maskload_else_operand): New predicate. * config/gcn/gcn-valu.md: Use new predicate.
2024-10-25gcc: Remove trailing whitespaceJakub Jelinek3-66/+66
I've tried to build stage3 with -Wleading-whitespace=blanks -Wtrailing-whitespace=blank -Wno-error=leading-whitespace=blanks -Wno-error=trailing-whitespace=blank added to STRICT_WARN and that expectably resulted in about 2744 unique trailing whitespace warnings and 124837 leading whitespace warnings when excluding *.md files (which obviously is in big part a generator issue). Others from that are generator related, I think those need to be solved later. The following patch just fixes up the easy case (trailing whitespace), which could be easily automated: for i in `find . -name \*.h -o -name \*.cc -o -name \*.c | xargs grep -l '[ ]$' | grep -v testsuite/`; do sed -i -e 's/[ ]*$//' $i; done I've excluded files which I knew are obviously generated or go FE. Is there anything else we'd want to avoid the changes? Due to patch size, I've split it between gcc/ part (this patch) and rest (include/, libiberty/, libgcc/, libcpp/, libstdc++-v3/). 2024-10-24 Jakub Jelinek <jakub@redhat.com> gcc/ * lra-assigns.cc:

2024-10-22GCN: Initial generic-target handling, add more GCN macro definesTobias Burnus7-32/+147
Newer llvm-mc assemblers support the gfx*-generic targets, permitting to generate code for all GPUs belonging to the same generation, even if not optimal code. This requires LLVM 19. This patch adds the compiler-side support for generic gfx and also adds -march=gfx10-3-generic and -march=gfx-11. However, those -march= are not documented nor used anywhere, yet. Disclaimer: Not tested (as my ROCm does not support it); additionally, libgomp/plugin/plugin-gcn.c has to be updated before it becomes useful. For better compatibility with LLVM's Clang, this commit additionally adds the macro definitions __GFX<9|10|11>__ for the architecture family, __AMDGPU__ besides the existing __AMDGCN__ and the two strings-containing macros __amdgcn_processor__ and __amdgcn_target_id__, where the former has '-' replaced by '_' but otherwise both contain the lower case name. For the new generic targets, the same happens, yielding, e.g., __gfx10_3_generic__. gcc/ChangeLog: * config/gcn/gcn-devices.def: Add generic version/flag as additional value and architecture family entry; update; add gfx-10-3-generic and gfx11-generic. * config/gcn/gcn-hsa.h (ABI_VERSION_SPEC): Remove (ASM_SPEC): Use generated ABI_VERSION_OPT instead. * config/gcn/gcn-tables.opt: Regenerate * config/gcn/gcn.h (gcn_device_def): Add generic_version and arch_family members.

2024-10-22amdgcn: Refactor device settings into a def fileAndrew Stubbs13-271/+476
Almost all device-specific settings are now centralised into gcn-devices.def for the compiler, mkoffload, and libgomp. No longer will we have to touch 10 files in multiple places just to add another device without any exotic features. (New ISAs and devices with incompatible metadata will continue to need a bit more.) In order to remove the device-specific conditionals in the code a new value HSACO_ATTR_UNSUPPORTED has been added, indicating that the assembler will reject any setting of that option. This incorporates some of Tobias's patch from March 2024. Co-Authored-By: Tobias Burnus <tburnus@baylibre.com> gcc/ChangeLog: * config.gcc (amdgcn): Add gcn-device-macros.h to tm_file.

2024-09-02amdgcn: Remove TARGET_GCN5_PLUSAndrew Stubbs5-135/+59
Now that GCN3 support is gone, TARGET_GCN5_PLUS always evaluates to true, so we can make that code unconditional, and remove all the "else" cases. The ISA features TARGET_GLOBAL_ADDRSPACE, TARGET_FLAT_OFFSETS, TARGET_EXPLICIT_CARRY, and TARGET_MULTIPLY_IMMEDIATE, are similarly also redundant and can be made unconditional. The naming of the "gcc_version" attribute has been confusing since the "rdna" attribute was added and this makes it worse, so it has been renamed to "cdna".

2024-06-25Replace {FLOAT,{,LONG_}DOUBLE}_TYPE_SIZE with new hook mode_for_floating_typeKewen Lin1-3/+0
Currently how we determine which mode will be used for a floating point type is that for a given type precision (size) call mode_for_size to get the first mode which has this size in the specified class. On Powerpc, we have three modes (TF/KF/IF) having the same mode precision 128 (see[1]), so the processing forces us to have to place TF at the first place, it would require us to make more adjustment in some generic code to avoid some unexpected mode conversions and it would be even worse if we get rid of TF eventually one day. And as Joseph pointed out in [2], "floating types should have their mode, not a poorly defined precision value", as Joseph and Richi suggested, this patch is to introduce one hook mode_for_floating_type which returns the corresponding mode for type float, double or long double. The default implementation returns SFmode for float and DFmode for double or long double. For ports which need special treatment, there are some other patches for their own port specific implementation (referring to how {,LONG_}DOUBLE_TYPE_SIZE get used there). For all generic uses of {FLOAT,{,LONG_}DOUBLE}_TYPE_SIZE, depending on the context, some of them are replaced with TYPE_PRECISION of the according type node, some other are replaced with GET_MODE_PRECISION on the mode from mode_for_floating_type. This patch also poisons {FLOAT,{,LONG_}DOUBLE}_TYPE_SIZE, so most defines of {FLOAT,{,LONG_}DOUBLE}_TYPE_SIZE in port specific are removed, but there are still some which are good to be kept for readability then they get renamed with port specific prefix.

2024-03-22amdgcn: Prefer V32 on RDNA devicesAndrew Stubbs1-0/+26
We run these devices in wavefrontsize64 for compatibility, but they actually only have 32-lane vectors, natively. If the upper part of a V64 is masked off (as it is in V32) then RDNA devices will skip execution of the upper part for most operations, so this adjustment shouldn't leave too much performance on the table. One exception is memory instructions, so full wavefrontsize32 support would be better. The advantage is that we avoid the missing V64 operations (such as permute and vec_extract). gcc/ChangeLog: * config/gcn/gcn.cc (gcn_vectorize_preferred_simd_mode): Prefer V32 on RDNA devices.

Also, add some safeguards for the future. Fix-up for commit 52a2c659ae6c21f84b6acce0afcb9b93b9dc71a0 "GCN: Add pre-initial support for gfx1100". gcc/ * config/gcn/gcn.h (TARGET_CPU_CPP_BUILTINS): Restore lost '__gfx90a__' target CPU definition. Add some safeguards for the future.
2024-02-15amdgcn: Disallow unsupported permute on RDNA devicesAndrew Stubbs2-8/+14
The RDNA architecture has limited support for permute operations. This should allow use of the permutations that do work, and fall back to linear code for other cases. gcc/ChangeLog: * config/gcn/gcn-valu.md (vec_extract<V_MOV:mode><V_MOV_ALT:mode>): Add conditions for RDNA. * config/gcn/gcn.cc (gcn_vectorize_vec_perm_const): Check permutation details are supported on RDNA devices.
2024-02-01GCN: Don't hard-code number of SGPR/VGPR/AVGPR registersThomas Schwinge2-6/+15
Also add 'STATIC_ASSERT's for number of SGPR/VGPR/AVGPR registers (in '#ifndef USED_FOR_TARGET', as otherwise 'STATIC_ASSERT' isn't available). gcc/ * config/gcn/gcn.cc (gcn_hsa_declare_function_name): Don't hard-code number of SGPR/VGPR/AVGPR registers. * config/gcn/gcn.h: Add a 'STATIC_ASSERT's for number of SGPR/VGPR/AVGPR registers.
