2017-11-19PR 44292 Handle large record lengthsJanne Blomqvist2-17/+29
Now that the ABI supports large record lengths, there's a few places in libgfortran where we need to use larger types. For internal units which by definition are in-memory, it's enought to use ptrdiff_t, for external units gfc_offset.

2017-11-17Add extra field to gtm_jmpbuf on x86 onlyIgor Tsimbalist3-21/+32
Expand the gtm_jmpbuf structure by one word field to add Intel CET support further. The code in sjlj.S already allocates more space on the stack then gtm_jmpbuf needs. Use this extra space to absorb the new field. The structure is allocated on the stack in such a way that eip/rsp field is overlapped with return address on the stack. Locate the new field right before eip/rsp so code that accesses buffer fields relative to address of gtm_jmpbuf has its offsets unchanged. * libitm/config/x86/target.h: Add new field (ssp). * libitm/config/x86/sjlj.S: Change offsets.

2017-11-17[AArch64] Adjust tuning parameters for FalkorLuis Machado2-2/+9
Disabling software prefetching and switching the autoprefetcher to weak improves CPU2017 rate and speed benchmarks for both int and fp sets on Falkor. SPECrate 2017 fp is up 0.38% SPECspeed 2017 fp is up 0.54% SPECrate 2017 int is up 3.02% SPECspeed 2017 int is up 3.16% There are only a couple individual regressions. The biggest one being about 4% in parest. For SPEC2006, we've noticed the following: SPECint is up 0.91% SPECfp is stable In the case of SPEC2006 we noticed both a big regression in mcf (about 20%) and a big improvement for hmmer (about 40%). Since the overall result is positive, we would like to make these new tuning settings the default for Falkor. We may revisit the software prefetcher setting in the future, in case we can adjust it enough so it provides us a good balance between improvements and regressions (mcf). But for now it is best if it stays off. 2017-11-17 Luis Machado <luis.machado@linaro.org> gcc/ * config/aarch64/aarch64.c (qdf24xx_prefetch_tune) <default_opt_level>: Set to -1.

2017-11-17Add Intel CET support for EH in libgcc.Igor Tsimbalist9-17/+148
Control-flow Enforcement Technology (CET), published by Intel, introduces the Shadow Stack feature, which ensures a return from a function is done to exactly the same location from where the function was called. When EH is present the control-flow transfer may skip some stack frames and the shadow stack has to be adjusted not to signal a violation of a control-flow transfer. It's done by counting a number of skiping frames and adjasting shadow stack pointer by this number. Having new semantic of the 'ret' instruction if CET is supported in HW the 'ret' instruction cannot be generated in ix86_expand_epilogue when we are returning after EH is processed. Added a code in ix86_expand_epilogue to adjust Shadow Stack pointer and to generate an indirect jump instead of 'ret'. As sp register is used during this adjustment thus the argument in pro_epilogue_adjust_stack is changed to update cfa_reg based on whether control-flow instrumentation is set. Without updating the cfa_reg field there is an assert later in dwarf2 pass related to mismatch the stack register and cfa_reg value. gcc/ * config/i386/i386.c (ix86_expand_epilogue): Change simple return to indirect jump for EH return if control-flow protection is enabled.

2017-11-17combine: Add added_notes_insnSegher Boessenkool2-7/+33
This patch makes combine reconsider insns it added notes to. This matters for example if the note is a REG_DEAD; without the note the setter of the register has to be kept around in the result of combinations, so it cannot be a 2->1 combination, and the cost of the result is higher than without that extra set, so try_combine may refuse the combination with the set, but allow it without the set. This fixes a regression for powerpc: pr69946.c has started to fail after the bitfield expansion changes. GCC used to generate lwz 3,0(9) rlwinm 3,3,12,20,23 ori 3,3,0x11 rotldi 3,3,52 bl bar but now it does lwz 3,0(9) rldicr 3,3,32,3 srdi 3,3,48 ori 3,3,0x110 sldi 3,3,48 bl bar (an instruction too many). After this patch it is lwz 3,0(9) rlwinm 3,3,16,16,19 ori 3,3,0x110 sldi 3,3,48 bl bar (the testcase still does not pass, it looks for very specific insns). * combine.c (added_notes_insn): New.

2017-11-17combine: Don't split insns if half is unused (PR82621)Segher Boessenkool2-1/+8
If we have a PARALLEL of two SETs, and one half is unused, we currently happily split that into two instructions (although the unused one is useless). Worse, as PR82621 shows, combine will happily merge this insn into I3 even if some intervening insn sets the same register again, which is wrong. This fixes it by not splitting PARALLELs with REG_UNUSED notes. It all is handled fine by combine in that case: just the "single set that is unused" case isn't handled properly. This also results in better code: combine will now actually throw away the unused SET. (It still won't do that in an I3).
