2017-01-07[-fcompare-debug] var tracking options are not optimization optionsAlexandre Oliva1-4/+4
If we include them in the ICF hash, they may cause congruence_groups to be processed in a different order due to different hashes, which in turn causes different funcdef_nos to be assigned to functions. Since these numbers are included in -fcompare-debug dumps, they cause failures. Since these options are not optimization options, in that they do not (or should not, save for bugs like this) affect the executable code output by the compiler, they should not be marked as such. This patch replaces the Optimization flag in the var-tracking options with the newly-introduced PerFunction flag, so that it can still be controlled on a per-function basis, but that disregards it in the hash computation used by ICF. This fixes -fcompare-debug failures in numerous LTO testcases. for gcc/ChangeLog * doc/options.texi (PerFunction): New. * opt-functions.awk (switch_flags): Map both Optimization and PerFunction to CL_OPTIMIZATION. * opth-gen.awk: Test for PerFunction flag along with Optimization. * optc-save-gen.awk: Likewise.

2016-10-31Add -Wshadow=global -Wshadow=local and -Wshadow=compatible-local.Le-Chun Wu1-1/+19
This patch from Le-Chun Wu adds two new shadow warning flags for C and C++: -Wshadow=local which warns if a local variable shadows another local variable or parameter, -Wshadow=compatible-local which warns if a local variable shadows another local variable or parameter whose type is compatible with that of the shadowing variable. It is already on the google/main branch (Google ref 39127) and was previously submitted by Diego Novillo and reviewed on http://codereview.appspot.com/4452058 I addressed the review comments and made the following changes: - Add -Wshadow=global (the default alias for -Wshadow). - Make the documented options -Wshadow=global, -Wshadow=local and -Wshadow=compatible-local (with hidden undocumented aliases -Wshadow-local and -Wshadow-compatible-local for compatibility). - The -Wshadow=global, -Wshadow=local and -Wshadow=compatible-local relationships are expressed in common.opt instead of in opts.c and documented in invoke.texi. - The "previous declaration" warnings were turned into notes and use the (now) existing infrastructure instead of duplicating the warnings. The testcases have been adjusted to expect the notes. - The conditional change in name-lookup.c for non-locals (where we don't want to change the warnings, but just check the global ones) has been dropped. - Use warning_at in c-decl.c (warn_if_shadowing). gcc/ChangeLog: 2016-10-30 Le-Chun Wu <lcwu@google.com> Mark Wielaard <mjw@redhat.com> * doc/invoke.texi: Document Wshadow-local and Wshadow-compatible-local. * common.opt (Wshadow=global): New option.

2016-06-03Add option for whether ceil etc. can raise "inexact", adjust x86 conditions.Joseph Myers1-0/+4
In ISO C99/C11, the ceil, floor, round and trunc functions may or may not raise the "inexact" exception for noninteger arguments. Under TS 18661-1:2014, the C bindings for IEEE 754-2008, these functions are prohibited from raising "inexact", in line with the general rule that "inexact" is only when the mathematical infinite precision result of a function differs from the result after rounding to the target type. GCC has no option to select TS 18661 requirements for not raising "inexact" when expanding built-in versions of these functions inline. Furthermore, even given such requirements, the conditions on the x86 insn patterns for these functions are unnecessarily restrictive. I'd like to make the out-of-line glibc versions follow the TS 18661 requirements; in the cases where this slows them down (the cases using x87 floating point), that makes it more important for inline versions to be used when the user does not care about "inexact". This patch fixes these issues. A new option -fno-fp-int-builtin-inexact is added to request TS 18661 rules for these functions; the default -ffp-int-builtin-inexact reflects that such exceptions are allowed by C99 and C11. (The intention is that if C2x incorporates TS 18661-1, then the default would change in C2x mode.) The x86 built-ins for rint (x87, SSE2 and SSE4.1) are made unconditionally available (no longer depending on -funsafe-math-optimizations or -fno-trapping-math); "inexact" is correct for noninteger arguments to rint. For floor, ceil and trunc, the x87 and SSE2 built-ins are OK if -ffp-int-builtin-inexact or -fno-trapping-math (they may raise "inexact" for noninteger arguments); the SSE4.1 built-ins are made to use ROUND_NO_EXC so that they do not raise "inexact" and so are OK unconditionally. Now, while there was no semantic reason for depending on -funsafe-math-optimizations, the insn patterns had such a dependence because of use of gen_truncxf<mode>2_i387_noop to truncate back to SFmode or DFmode after using frndint in XFmode. In this case a no-op truncation is safe because rounding to integer always produces an exactly representable value (the same reason why IEEE semantics say it shouldn't produce "inexact") - but of course that insn pattern isn't safe because it would also match cases where the truncation is not in fact a no-op. To allow frndint to be used for SFmode and DFmode without that unsafe pattern, the relevant frndint patterns are extended to SFmode and DFmode or new SFmode and DFmode patterns added, so that the frndint operation can be represented in RTL as an operation acting directly on SFmode or DFmode without the extension and the problematic truncation. A generic test of the new option is added, as well as x86-specific tests, both execution tests including the generic test with different x86 options and scan-assembler tests verifying that functions that should be inlined with different options are indeed inlined. I think other architectures are OK for TS 18661-1 semantics already. Considering those defining "ceil" patterns: aarch64, arm, rs6000, s390 use instructions that do not raise "inexact"; nvptx does not support floating-point exceptions. (This does mean the -f option in fact only affects one architecture, but I think it should still be a -f option; it's logically architecture-independent and is expected to be affected by future -std options, so is similar to e.g. -fexcess-precision=, which also does nothing on most architectures but is implied by -std options.)

We can't set flag_pie to the default when flag_pic == 0, which may be set by -fno-pic or -fno-PIC, since the default value of flag_pie is non-zero when GCC is configured with --enable-default-pie.
