2020-08-03Removal of HSA offloading from gcc and libgompMartin Jambor90-21260/+516
This patch removes the generation of HSAIL from the compiler, the HSA offloading plugin from libgomp and the associated testsuite tests and infrastructure bits from the respective testsuites. Apart from removal of the obvious files, I removed bits that I found by searching for HSA related terms and by re-tracing my steps and looking at the patches that introduced HSA in the first place. I did not remove everything these patches brought in, for example: - the mechanism to pass offload-target specific info from the application to the offloading plugin - but the same mechanism is also used to communicate number of teams and the thread limit to all offload targets. - run_func hook in gomp_device_descr stays too, although now it is not used. If some future offload target would like the ability to refuse to offload some functions, it can use it. It is easy to remove as a follow-up if it is considered clutter, though. - configure options --with-hsa-runtime=PATH, -with-hsa-runtime-include=PATH and --with-hsa-runtime-lib=PATH rmeain because GCN uses them too. - Surprisingly, GOMP_TARGET_ARG_HSA_KERNEL_ATTRIBUTES (a constant from gomp-constants.h) appears in the source of the amdgcn libgomp plugin, although I tend to think that code path is not ever used and this patch certainly removes it from the compiler. Nevertheless, it seems it has potential value beyond HSAIL and so I've kept it, it can of course always be easily removed in the future of GCN folk abandon it too. - I assume constants OFFLOAD_TARGET_TYPE_HSA and GOMP_DEVICE_HSA need to stay indefinitely too just so that no future offload target picks that number. - I have kept dg-require-effective-target offload_device_nonshared_as requirement of thests which have it. It is quite probable I missed some small HSA artifacts but those should be easy to remove later as we find them. include/ChangeLog: 2020-07-24 Martin Jambor <mjambor@suse.cz> * gomp-constants.h (GOMP_VERSION_HSA): Remove. gcc/ChangeLog: 2020-07-24 Martin Jambor <mjambor@suse.cz> * hsa-brig-format.h: Moved to brig/brigfrontend. * hsa-brig.c: Removed. * hsa-builtins.def: Likewise. * hsa-common.c: Likewise. * hsa-common.h: Likewise. * hsa-dump.c: Likewise. * hsa-gen.c: Likewise. * hsa-regalloc.c: Likewise. * ipa-hsa.c: Likewise. * omp-grid.c: Likewise. * omp-grid.h: Likewise. * Makefile.in (BUILTINS_DEF): Remove hsa-builtins.def.

2020-08-03regrename: Avoid disrupting SMS schedule [PR95696]Yunde Zhong2-4/+14
SMS is performed before reload, and each insn in SMS schedule uses pseudo-register. After reload, regrename pass try to adjust the hard registers with def/use chain created by build_def_use. For now, regrename pass isn't aware of VLIW bundles created by SMS, it may updated a register which may not be really unused, which will causes invalid VLIW bundles. Before the final schedule, we recheck the validation of VLIW bundles and reschedule the conflicted insns to avoid the above issue. Rescheduling the conflicted insns will destroy SMS schedule of the kernel loop, which would be harmful to performance. 2020-08-03 Yunde Zhong <zhongyunde@huawei.com> gcc/ PR rtl-optimization/95696 * regrename.c (regrename_analyze): New param include_all_block_p with default value TRUE.

2020-08-03genmatch: Avoid unused parameter warnings in generated code.Roger Sayle1-1/+29
This patch silences a number of unused parameter warnings whilst compiling both generic-match.c and gimple-match.c. The problem is that multiple (polymorphic) functions are generated for generic_simplify and gimple_simplify, each handling tree codes with a specific number of children. Currently, there are no simplifications for tree codes with four or five children, leading to functions with "empty" bodies and unused function arguments. This patch detects those cases, and generates stub functions (with anonymous arguments) to silence these warnings. 2020-08-03 Roger Sayle <roger@nextmovesoftware.com> gcc/ChangeLog * genmatch.c (decision_tree::gen): Emit stub functions for tree code operand counts that have no simplifications.

2020-08-03AArch64: Fix hwasan failure in readline.Tamar Christina1-2/+8
My previous fix added an unchecked call to fgets in the new function readline. fgets can fail when there's an error reading the file in which case it returns NULL. It also returns NULL when the next character is EOF. The EOF case is already covered by the existing code but the error case isn't. This fixes it by returning the empty string on error. Also I now use strnlen instead of strlen to make sure we never read outside the buffer. This was flagged by Matthew Malcomson during his hwasan work. gcc/ChangeLog: * config/aarch64/driver-aarch64.c (readline): Check return value fgets.

2020-08-02var-tracking: fix uninitialised use of 'in_pending' [PR96404]Sergei Trofimovich1-0/+1
r11-2447-g:1212cfad093 ("Improve var-tracking dataflow iteration order") changed 'in_pending' initialization from: in_pending = sbitmap_alloc (last_basic_block_for_fn (cfun)); bitmap_ones (in_pending); to more complex partial bit population algorithm. Due to presence of uninitialized bits gcc started injecting extra debug entries in seemigly arbitrary locations and started failing stage2/stage3 bootstrap comparison. valgrind detected unilitialized bits as: Conditional jump or move depends on uninitialised value(s) at 0xDBED3B: vt_find_locations() (var-tracking.c:7230) by 0xDBF2FB: variable_tracking_main_1() (var-tracking.c:10519) ...

2020-08-01c: Fix bogus vector initialisation error [PR96377]Richard Sandiford12-15/+317
One of the problems in this PR was that if we had: vector_type1 array[] = { vector_value1 }; process_init_element would only treat vector_value1 as initialising a vector_type1 if they had the same TYPE_MAIN_VARIANT. This has several problems: (1) It gives confusing error messages if the vector types are incompatible. (Tested by gcc.dg/pr96377-1.c.) (2) It means that we reject code that should be valid with -flax-vector-conversions. (Tested by gcc.dg/pr96377-2.c.) (3) On arm and aarch64 targets, it means that we reject some initializers that mix Advanced SIMD and standard GNU vectors. These vectors have traditionally had different TYPE_MAIN_VARIANTs because they have different mangling schemes. (Tested by gcc.dg/pr96377-[3-6].c.) (4) It means that we reject SVE initializers that should be valid. (Tested by gcc.target/aarch64/sve/gnu_vectors_[34].c.) (5) After r11-1741-g:31427b974ed7b7dd54e2 we reject: arm_neon_type1 array[] = { k ^ arm_neon_value1 }; because applying the binary operator to arm_neon_value1 strips the "Advanced SIMD type" attributes that were added in that patch. Stripping the attributes is problematic for other reasons though, so that still needs to be fixed separately. g++.target/aarch64/sve/gnu_vectors_[34].C already pass. gcc/c/ PR c/96377 * c-typeck.c (process_init_element): Split test for whether to recurse into a record, union or array into...

Rewrite code sequences throughout the 64-bit RISC-V `__riscv_save_*' routines replacing `li t1, -48', `li t1, -64', and `li t1, -80', instructions, which do not have a compressed encoding, respectively with `li t1, 3', `li t1, 4', and `li t1, 4', which do, and then adjusting the remaining code accordingly observing that `sub sp, sp, t1' takes the same amount of space as an `slli t1, t1, 4'/`add sp, sp, t1' instruction pair does, again due to the use of compressed encodings, saving 6 bytes total. This change does increase code size by 4 bytes for RISC-V processors lacking the compressed instruction set, however their users couldn't care about the code size or they would have chosen an implementation that does have the compressed instructions, wouldn't they? libgcc/ * config/riscv/save-restore.S [__riscv_xlen == 64] (__riscv_save_10, __riscv_save_8, __riscv_save_6, __riscv_save_4) (__riscv_save_2): Replace negative immediates used for the final stack pointer adjustment with positive ones, right-shifted by 4.

2020-07-31c++: Use error_at rather than warning_at for missing return in constexpr ↵Jakub Jelinek6-39/+55
functions [PR96182] For C++11 we already emit an error if a constexpr function doesn't contain a return statement, because in C++11 that is the only thing it needs to contain, but for C++14 we would normally issue a -Wreturn-type warning. As mentioned by Jonathan, such constexpr functions are invalid, no diagnostics required, because there doesn't exist any arguments for which it would result in valid constant expression. This raises it to an error in such cases. The !LAMBDA_TYPE_P case is to avoid error on g++.dg/pr81194.C where the user didn't write constexpr anywhere and the operator() is compiler generated. 2020-07-31 Jakub Jelinek <jakub@redhat.com> PR c++/96182 * decl.c (finish_function): In constexpr functions use for C++14 and later error instead of warning if no return statement is present and diagnose it regardless of warn_return_type.

2020-07-31nvptx: Define TARGET_TRULY_NOOP_TRUNCATION to falseRoger Sayle2-23/+22
Many thanks to Richard Biener for approving the midde-end patch that cleared the way for this one. This nvptx patch defines the target hook TARGET_TRULY_NOOP_TRUNCATION to false, indicating that integer truncations require explicit instructions. nvptx.c already defines TARGET_MODES_TIEABLE_P and TARGET_CAN_CHANGE_MODE_CLASS to false, and as (previously) documented that may require TARGET_TRULY_NOOP_TRUNCATION to be defined likewise. This patch decreases the number of unexpected failures in the testsuite by 10, and increases the number of expected passes by 4, including these previous FAILs/ICEs: gcc.c-torture/compile/opout.c gcc.dg/torture/pr79125.c gcc.dg/tree-ssa/pr92085-1.c Unfortunately there is one testsuite failure that used to pass gcc.target/nvptx/v2si-cvt.c, but this isn't an ICE or incorrect code. This regression has been filed as PR96403, and the failing scan-assembler directives have been replaced by a reference to the PR. This patch has been tested on nvptx-none hosted on x86_64-pc-linux-gnu with "make" and "make check" with fewer ICEs and no wrong code regressions. 2020-07-31 Roger Sayle <roger@nextmovesoftware.com> Tom de Vries <tdevries@suse.de> gcc/ChangeLog: PR target/90928 * config/nvptx/nvptx.c (nvptx_truly_noop_truncation): Implement. (TARGET_TRULY_NOOP_TRUNCATION): Define. gcc/testsuite/ChangeLog: * gcc.target/nvptx/v2si-cvt.c: Simplify source. Remove scan-assembler directives. Mention PR96403.
