2017-12-14[arm] Add -mverbose-cost-dump and de-verbosify cost dumpsKyrylo Tkachov3-1/+10
This patch adds an -mverbose-cost-dump option, similar to the one in aarch64. It makes the RTX cost dump print the RTX we're costing in the backend, as well as its cost. This can be distracting in other cost-related RTL dumps like combine's. So now we don't dump the backend information by default, but provide the power-user option -mverbose-cost-dump to enable the old verbose dumping. This option is for GCC developers debugging the compiler only, so no documentation are added. It's also trivially simple in functionality so no test is added either. Bootstrapped and tested on arm-none-linux-gnueabihf. Committed to trunk. * config/arm/arm.opt (mverbose-cost-dump): New option. * config/arm/arm.c (arm_rtx_costs): Use it. From-SVN: r255644

2017-12-14[compare-debug] use call loc for nop_endbrAlexandre Oliva2-8/+15
We skip debug insns and notes after a call that needs a nop_endbr, but since a debug insn could be the last in a block, it may affect the loc in the emitted nop_endbr insn. Although this has no effect on codegen, it does mess with debug info a bit, and it causes -fcompare-debug to fail for e.g. libsanitizer's tsan/tsan_platform_linux.cc on x86_64. So, pick the location of the call insn for the nop_endbr insn, to avoid the line number differences in dumps, including -fcompare-debug ones. Also, we don't need to determine what the insert point would be unless we're actually emitting the nop_endbr insn after the call, so rearrange the code to avoid wasting cycles. Finally, it seems like testing for barriers is a mistake. We probably never actually pass that test, for the barriers would hit BB_END first. If we did, we'd end up emitting the nop_endbr outside any BB, even after the end of the function! That would be Very Bad (TM). Now, since the test as it is can't hurt, I figured I wouldn't change the logic right now, just add a comment so that someone involved in endbr stuff can have a second look and hopefully fix it. for gcc/ChangeLog * config/i386/i386.c (rest_of_insert_endbranch): Use call loc for its nop_endbr.

2017-12-14[PATCH PR81228][AARCH64]Fix ICE by adding LTGT in vec_cmp<mode><v_int_equiv>Sudakshina Das5-1/+46
This patch is a follow up to the existing discussions on https://gcc.gnu.org/ml/gcc-patches/2017-07/msg01904.html Bin had earlier submitted this patch to fix the ICE that occurs because of the missing LTGT in aarch64-simd.md. That discussion opened up a new bug report PR81647 for an inconsistent behavior. As discussed earlier on the gcc-patches discussion and on the bug report, PR81647 was occurring because of how UNEQ was handled in aarch64-simd.md rather than LTGT. Since __builtin_islessgreater is guaranteed to not give an FP exception but LTGT might, __builtin_islessgreater gets converted to ~UNEQ very early on in fold_builtin_unordered_cmp. Thus I will post a separate patch for correcting how UNEQ and other unordered comparisons are handled in aarch64-simd.md. This patch is only adding the missing LTGT to plug the ICE. Testing done: Checked for regressions on bootstrapped aarch64-none-linux-gnu and added a new compile time test case that gives out LTGT to make sure it doesn't ICE *** gcc/ChangeLog *** 2017-12-14 Sudakshina Das <sudi.das@arm.com> Bin Cheng <bin.cheng@arm.com> PR target/81228 * config/aarch64/aarch64.c (aarch64_select_cc_mode): Move LTGT to CCFPEmode. * config/aarch64/aarch64-simd.md (vec_cmp<mode><v_int_equiv>): Add LTGT. *** gcc/testsuite/ChangeLog *** 2017-12-14 Sudakshina Das <sudi.das@arm.com> PR target/81228 * gcc.dg/pr81228.c: New.

2017-12-14poly_int: add poly-int.hRichard Sandiford28-12/+8871
This patch adds a new "poly_int" class to represent polynomial integers of the form: C0 + C1*X1 + C2*X2 ... + Cn*Xn It also adds poly_int-based typedefs for offsets and sizes of various precisions. In these typedefs, the Ci coefficients are compile-time constants and the Xi indeterminates are run-time invariants. The number of coefficients is controlled by the target and is initially 1 for all ports. Most routines can handle general coefficient counts, but for now a few are specific to one or two coefficients. Support for other coefficient counts can be added when needed. The patch also adds a new macro, IN_TARGET_CODE, that can be set to indicate that a TU contains target-specific rather than target-independent code. When this macro is set and the number of coefficients is 1, the poly-int.h classes define a conversion operator to a constant. This allows most existing target code to work without modification. The main exceptions are: - values passed through ..., which need an explicit conversion to a constant - ?: expression in which one arm ends up being a polynomial and the other remains a constant. In these cases it would be valid to convert the constant to a polynomial and the polynomial to a constant, so a cast is needed to break the ambiguity. The patch also adds a new target hook to return the estimated value of a polynomial for costing purposes. The patch also adds operator<< on wide_ints (it was already defined for offset_int and widest_int). I think this was originally excluded because >> is ambiguous for wide_int, but << is useful for converting bytes to bits, etc., so is worth defining on its own. The patch also adds operator% and operator/ for offset_int and widest_int, since those types are always signed. These changes allow the poly_int interface to be more predictable. I'd originally tried adding the tests as selftests, but that ended up bloating cc1 by at least a third. It also took a while to build them at -O2. The patch therefore uses plugin tests instead, where we can force the tests to be built at -O0. They still run in negligible time when built that way. 2017-12-14 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * poly-int.h: New file. * poly-int-types.h: Likewise. * coretypes.h: Include them.
