[PATCH 2/2 v2] rs6000: Guard density_test only for vector version

Hi, v1: https://gcc.gnu.org/pipermail/gcc-patches/2021-May/569790.html This is the updated version with one new parameter costing_for_scalar passed by init_cost hook, instead of checking the passed data point identity. Bootstrapped/regtested on powerpc64le-linux-gnu P9. Is it ok for trunk? BR,

[PATCH] rs6000: Move rs6000_vect_nonmem into target cost_data

Hi, This patch is to move rs6000_vect_nonmem (target cost_data related information) into target cost_data struct. Following Richi's comments in the thread[1], we can gather data from add_stmt_cost invocations. This is one pre-step to centralize target cost_data related stuffs. Is it ok for trun

[PATCH v5 1/2] MIPS: Not trigger error for pre-R6 and -mcompact-branches=always

For MIPSr6, we may wish to use compact-branches only. Currently, we have to use `always' option, while it is mark as conflict with pre-R6. cc1: error: unsupported combination: ‘mips32r2’ -mcompact-branches=always Just ignore -mcompact-branches=always for pre-R6. This patch also defines __mip

[PATCH v5 2/2] MIPS: add builtime option for -mcompact-branches

For R6+ target, it allows to configure gcc to use compact branches only if avaiable. gcc/ChangeLog: * config.gcc: add -with-compact-branches=policy build option. * doc/install.texi: Likewise. * config/mips/mips.h: Likewise. --- gcc/config.gcc | 13 +++-- gc

[PATCH v2] MIPS: R6: load/store can process unaligned address

MIPS release 6 requires the lw/ld/sw/sd can work with unaligned address, while it can be implemented by full hardware or trap&emulate. Since it is may be fully done by hardware, we add an option -m(no-)unaligned-access, the kernel may need it. gcc/ChangeLog: * config/mips/mips.h (ISA_HAS

[GOVERNANCE] Where to file complaints re project-maintainers?

(failed to join gcc, so posting here) Is there any private email where one can file complaints re project-maintainers (or "those who are supervising the maintainers") ? Is there any information about the process for such complaints? Related Issue: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100

[patch] Remove call to gcc_unreachable in range-op.cc

Hi, the attached Ada testcase happens to stumble on the call to gcc_unreachable in operator_bitwise_xor::op1_range. My understanding is that there is nothing wrong going on and that it's safe to let it go through. Tested on x86-64/Linux, OK for mainline and 11 branch? 2021-05-08 Eric Botcaz
