2019-06-19compiler: optimize string concatenationsIan Lance Taylor4-83/+23
runtime.concatstring{2,3,4,5} are just wrappers of concatstrings. These wrappers don't provide any benefit, at least in the C calling convention we use, where passing arrays by value isn't an efficient thing. Change it to always use concatstrings. Also, the cap field of the slice passed to concatstrings is not necessary. So change it to pass a pointer and a length directly, which is more efficient than passing a slice header by value.

2019-06-19Simplify setjmp and non-local goto implementation (PR84521)Wilco Dijkstra14-291/+91
This fixes and simplifies the setjmp and non-local goto implementation. Currently the virtual frame pointer is saved when using __builtin_setjmp or a non-local goto. Depending on whether a frame pointer is used, this may either save SP or FP with an immediate offset. However the goto or longjmp always updates the hard frame pointer. A receiver veneer in the original function then assigns the hard frame pointer to the virtual frame pointer, which should, if it works correctly, again assign SP or FP. However the special elimination code in eliminate_regs_in_insn doesn't do this correctly unless the frame pointer is used, and even if it worked by writing SP, the frame pointer would still be corrupted. A much simpler implementation is to always save and restore the hard frame pointer. This avoids 2 redundant instructions which add/subtract the virtual frame offset. A large amount of code can be removed as a result, including all implementations of TARGET_BUILTIN_SETJMP_FRAME_VALUE (all of which already use the hard frame pointer). The expansion of nonlocal_goto on PA can be simplied to just restore the hard frame pointer. This fixes the most obvious issues, however there are still issues on targets which define HARD_FRAME_POINTER_IS_FRAME_POINTER (arm, mips). Each function could have a different hard frame pointer, so a non-local goto may restore the wrong frame pointer (TARGET_BUILTIN_SETJMP_FRAME_VALUE could be useful for this). The i386 TARGET_BUILTIN_SETJMP_FRAME_VALUE was incorrect: if stack_realign_fp is true, it would save the hard frame pointer value but restore the virtual frame pointer which according to ix86_initial_elimination_offset can have a non-zero offset from the hard frame pointer. The ia64 implementation of nonlocal_goto seems incorrect since the helper function moves the the frame pointer value into the static chain register (so this patch does nothing to make it better or worse).

For string concatenation, string to/from byte or rune slice conversion, and int to string conversion, if the result does not escape, we can allocate a small (32-element, or 4-byte for int to string) buffer on stack, and pass it to the runtime function.

2019-06-18[AArch64] Add a new CC mode for SVE conditionsRichard Sandiford14-70/+123
The SVE ACLE patches need to introduce a new CC_NZC mode for the conditions that can be tested after a PTRUE. In particular, LT needs to map to "mi"/"first" and GE to "pl"/"nfrst", instead of the normal CC mapping. Another advantage of using a separate mode is that we can print the SVE names of the conditions, which makes the output a bit easier to read. It therefore seems like an independent improvement that can go in now. The patch also avoids using (compare X (const_int 0)), because that gets folded away when used with LTU and GEU ("cc"/"last" and "cs"/"nlast"). Just using an unspec should be OK. The full set of conditions can't be tested without other SVE ACLE patches. 2019-06-18 Richard Sandiford <richard.sandiford@arm.com> gcc/ * config/aarch64/aarch64-modes.def (CC_NZC): New CC_MODE. * config/aarch64/aarch64-sve.md (*<optab><mode>3_cc) (ptest_ptrue<mode>, while_ult<GPI:mode><PRED_ALL:mode>) (*while_ult<GPI:mode><PRED_ALL:mode>_cc, *cmp<cmp_op><mode>) (*cmp<cmp_op><mode>_ptest, *cmp<cmp_op><mode>_cc) (*pred_cmp<cmp_op><mode>_combine, *pred_cmp<cmp_op><mode>) (vec_cmp<mode><vpred>, vec_cmpu<mode><vpred>, cbranch<mode>4): Use CC_NZC instead of CC. * config/aarch64/aarch64.md (condjump): Print a '.' in SVE conditions. * config/aarch64/aarch64.c (aarch64_sve_condition_codes): New variable.

2019-06-18Restore correct iv step for fully-masked loopsRichard Sandiford3-32/+37
r272233 introduced a large number of execution failures on SVE. The patch hard-coded an IV step of VF, but for SLP groups it needs to be VF * group size. Also, iv_precision had type widest_int but only needs to be unsigned int. 2019-06-18 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-vect-loop-manip.c (vect_set_loop_masks_directly): Remove vf parameter. Restore the previous iv step of nscalars_step, but give it iv_type rather than compare_type. Tweak code order to match the comments. (vect_set_loop_condition_masked): Update accordingly. * tree-vect-loop.c (vect_verify_full_masking): Use "unsigned int" for iv_precision. Tweak comment formatting. From-SVN: r272411
