2023-03-03c++, v3: Emit fundamental tinfos for _Float16/decltype(0.0bf16) types on ↵Jakub Jelinek2-0/+11
ia32 with -mno-sse2 [PR108883] _Float16 and decltype(0.0bf16) types are on x86 supported only with -msse2. On x86_64 that is the default, but on ia32 it is not. We should still emit fundamental type tinfo for those types in libsupc++.a/libstdc++.*, regardless of whether libsupc++/libstdc++ is compiled with -msse2 or not, as user programs can be compiled with different ISA flags from libsupc++/libstdc++ and if they are compiled with -msse2 and use std::float16_t or std::bfloat16_t and need RTTI for it, it should work out of the box. Furthermore, libstdc++ ABI on ia32 shouldn't depend on whether the library is compiled with -mno-sse or -msse2. Unfortunately, just hacking up libsupc++ Makefile/configure so that a single source is compiled with -msse2 isn't appropriate, because that TU emits also code and the code should be able to run on CPUs which libstdc++ supports. We could add [[gnu::attribute ("no-sse2")]] there perhaps conditionally, but it all gets quite ugly. The following patch instead adds a target hook which allows the backend to temporarily tweak registered types such that emit_support_tinfos emits whatever is needed. Additionally, it makes emit_support_tinfos_1 call emit_tinfo_decl immediately, so that temporarily created dummy types for emit_support_tinfo purposes only can be nullified again afterwards. And removes the previous fallback_* types used for dfloat*_type_node tinfos even when decimal types aren't supported. 2023-03-03 Jakub Jelinek <jakub@redhat.com> PR target/108883 gcc/ * target.h (emit_support_tinfos_callback): New typedef. * targhooks.h (default_emit_support_tinfos): Declare. * targhooks.cc (default_emit_support_tinfos): New function. * target.def (emit_support_tinfos): New target hook. * doc/tm.texi.in (emit_support_tinfos): Document it. * doc/tm.texi: Regenerated. * config/i386/i386.cc (ix86_emit_support_tinfos): New function.

2023-02-28ubsan: Honor -fstrict-flex-arrays= in -fsanitize=bounds [PR108894]Jakub Jelinek1-4/+7
While this isn't really a regression, the -fstrict-flex-arrays* option is new in GCC 13 and so I think we should make -fsanitize=bounds play with it well from the beginning. The current behavior is that -fsanitize=bounds considers all trailing arrays as flexible member-like arrays and both -fsanitize=bounds and -fsanitize=bounds-strict because of a bug don't even instrument [0] arrays at all, not as trailing nor when followed by other members. I think -fstrict-flex-arrays* options can be considered as language mode changing options, by default flexible member-like arrays are handled like flexible arrays, but that option can change the set of the arrays which are treated like that. So, -fsanitize=bounds should change with that on what is considered acceptable and what isn't. While -fsanitize=bounds-strict should reject them all always to continue previous behavior. The following patch implements that. To support [0] array instrumentation, I had to change the meaning of the bounds argument to .UBSAN_BOUNDS, previously it was the TYPE_MAX_VALUE of the domain unless ignore_off_by_one (used for taking address of the array element rather than accessing it; in that case 1 is added to the bound argument) and the later lowered checks were if (index > bound) report_failure (). The problem with that is that for [0] arrays where (at least for C++) the max value is all ones, for accesses that condition will be never true; for addresses of elements it was working (in C++) correctly before. This patch changes it to add 1 + ignore_off_by_one, so -1 becomes 0 or 1 for &array_ref and changing the lowering to be if (index >= bound) report_failure (). Furthermore, as C represents the [0] arrays with NULL TYPE_MAX_VALUE, I treated those like the C++ ones. 2023-02-28 Jakub Jelinek <jakub@redhat.com> PR sanitizer/108894 gcc/ * ubsan.cc (ubsan_expand_bounds_ifn): Emit index >= bound comparison rather than index > bound. * gimple-fold.cc (gimple_fold_call): Use tree_int_cst_lt rather than tree_int_cst_le for IFN_UBSAN_BOUND comparison. * doc/invoke.texi (-fsanitize=bounds): Document that whether flexible array member-like arrays are instrumented or not depends on -fstrict-flex-arrays* options of strict_flex_array attributes.

2023-02-25modula-2 module registration process seems to fail with shared libraries ↵Gaius Mulley1-6/+21
[PR108261] The commit adds pathnames to modula-2 which in turn appears in any external symbol. This is necessary to allow different dialects of libraries to coexist (different implementations of SYSTEM and Storage for example in libm2pim and libm2iso). It also makes it easier to debug as the library name forms part of the external mangled name. By default pathnames are not user facing.

2023-02-23**/*.texi: Reorder index entriesArsen Arsenović13-571/+570
This change is a generalization of r13-6292-gddf6fe375d9110. Historically, makeinfo exhibited a bug, due to which a structure like: @item foo @cindex foo @cindex bar ... would be transformed into an item heading, with the first index entry on it, followed by an item body, with the second index entry in it. This has often lead to index entries not linking to relevant items, but rather, just below them. This bug was exhibited in both Info and HTML documentation, and was most glaringly obvious in the latter. After a discussion with the Texinfo developers, it was decided that the appropriate construct for this case is: @cindex foo @cindex bar @item foo ... which behaves correctly in newer versions, linking all the index entries to the item itself. This pattern also produces copiable anchors in HTML output. This commit fixes most indices to follow the pattern above, however, omits relevant changes in the Ada manuals, as the algorithm described below lead to many false positives and unwanted changes in that manual. Much like the previous commit, this change is mostly mechanical, with a simple script. I have, however, gone over the patch myself also, to see if there's anything that ought to be kept as-is.

2023-02-21analyzer: stop exploring the path after certain diagnostics [PR108830]David Malcolm1-0/+25
PR analyzer/108830 reports a situation in which there are lots of followup -Wanalyzer-null-dereference warnings after the first access of a NULL pointer, leading to very noisy output from -fanalyzer. The analyzer's logic for stopping emitting multiple warnings from a state machine doesn't quite work for NULL pointers: it attempts to transition the malloc state machine's NULL pointer to the "stop" state, which doesn't seem to make much sense in retrospect, and seems to get confused over types. Similarly, poisoned_value_diagnostic can be very noisy for uninit variables, emitting a warning for every access to an uninitialized variable. In theory, region_model::check_for_poison makes some attempts to suppress followups, but only for the symbolic value itself; if the user's code keeps accessing the same region, we would get a warning on each one. For example, this showed up in Doom's s_sound.c where there were 7 followup uninit warnings after the first uninit warning in "S_ChangeMusic". This patch adds an extra mechanism, giving pending diagnostics the option of stopping the analysis of an execution path if they're saved for emission on it, and turning this on for these warnings: -Wanalyzer-null-dereference -Wanalyzer-null-argument -Wanalyzer-use-after-free -Wanalyzer-use-of-pointer-in-stale-stack-frame -Wanalyzer-use-of-uninitialized-value Doing so should hopefully reduce the cascades of diagnostics that -fanalyzer can sometimes emit. I added a -fno-analyzer-suppress-followups for the cases where you really want the followup warnings (e.g. in some DejaGnu tests, and for microbenchmarks of UB detection, such as PR analyzer/104224). Integration testing shows this patch reduces the number of probable false positives reported by 94, and finds one more true positive: Comparison: 9.34% -> 10.91% GOOD: 66 -> 67 (+1) BAD: 641 -> 547 (-94) where the affected warnings/projects are: -Wanalyzer-null-dereference: 0.00% GOOD: 0 BAD: 269 -> 239 (-30) Unclassified: 257 -> 228 (-29) apr-1.7.0: 12 -> 5 (-7) doom: 1 -> 0 (-1) haproxy-2.7.1: 47 -> 41 (-6) ImageMagick-7.1.0-57: 13 -> 9 (-4) qemu-7.2.0: 165 -> 154 (-11) Known false: 7 -> 6 (-1) xz-5.4.0: 4 -> 3 (-1) -Wanalyzer-use-of-uninitialized-value: 0.00% GOOD: 0 BAD: 143 -> 80 (-63) Known false: 47 -> 16 (-31) doom: 42 -> 11 (-31) Unclassified: 96 -> 64 (-32) coreutils-9.1: 14 -> 10 (-4) haproxy-2.7.1: 29 -> 23 (-6) qemu-7.2.0: 48 -> 26 (-22) -Wanalyzer-null-argument: 0.00% -> 2.33% GOOD: 0 -> 1 (+1) BAD: 43 -> 42 (-1) Unclassified: 39 -> 38 (-1) due to coreutils-9.1: 9 -> 8 (-1) True positive: 0 -> 1 (+1) (in haproxy-2.7.1) gcc/analyzer/ChangeLog: PR analyzer/108830 * analyzer.opt (fanalyzer-suppress-followups): New option. * engine.cc (impl_region_model_context::warn): Terminate the path if the diagnostic's terminate_path_p vfunc returns true and -fanalyzer-suppress-followups is true (the default).

2023-01-27doc: Fix up return type of __builtin_va_arg_pack_len [PR108560]Jakub Jelinek1-1/+1
__builtin_va_arg_pack_len as implemented returned int since its introduction in 2007. The initial documentation didn't mention any return type, which changed in 2010 in r0-103077-gab940b73bfabe2cec4 during some documentation formatting cleanups https://gcc.gnu.org/legacy-ml/gcc-patches/2010-09/msg01632.html I can understand that for formatting some type was needed there but what exactly hasn't been really discussed. So, I think we should change documentation to match the implementation, rather than change implementation to match the documentation. Most people don't use more than 2147483647 arguments to inline functions, and on poor targets with 16-bit ints I bet even having more than 65535 arguments to inline functions would be highly unexpected. 2023-01-27 Jakub Jelinek <jakub@redhat.com> PR other/108560 * doc/extend.texi: Fix up return type of __builtin_va_arg_pack_len from size_t to int.

2023-01-23install.texi: Bump newlib version for nvptx + gcnTobias Burnus1-2/+2
Before, newlib 3.2 was required for amdgcn and 3.1 for nvptx. Now recommended is 4.3.0 which was just released on 2023-01-20. While currently the old versions would work fine, upcoming GCC changes depend on a newer newlib. Thus, the minimal version is bumped instead of just recommending the new version. For GCN, the bump is in preparation for permitting non-threadlocal stack variables and vectorized math functions - both scheduled for GCC 13 and added to newlib in 4.3.0. For nvptx, this includes an emulated clock (commit 6bb96d13a), a calloc fix (5fca4e0f1) and changes to permit libgfortran to be compiled with I/O support instead of only in minimal mode. (Patch approved for GCC 13 but pending on a nvtpx patch, which for which review is pending.) gcc/ChangeLog: * doc/install.texi (amdgcn, nvptx): Require newlib 4.3.0.

2023-01-13Fix support for atomic loads and stores on hppa.John David Anglin1-66/+105
This change updates the atomic libcall support to fix the following issues: 1) A internal compiler error with -fno-sync-libcalls. 2) When sync libcalls are disabled, we don't generate libcalls for libatomic. 3) There is no sync libcall support for targets other than linux. As a result, non-atomic stores are silently emitted for types smaller or equal to the word size. There are now a few atomic libcalls in the libgcc code, so we need sync support on all targets. 2023-01-13 John David Anglin <danglin@gcc.gnu.org> gcc/ChangeLog: * config/pa/pa-linux.h (TARGET_SYNC_LIBCALL): Delete define. * config/pa/pa.cc (pa_init_libfuncs): Use MAX_SYNC_LIBFUNC_SIZE define. * config/pa/pa.h (TARGET_SYNC_LIBCALLS): Use flag_sync_libcalls.
