2020-11-30[Obvious] arm: Fix test from failing on some targets [PR91816]Stam Markianos-Wright1-2/+3
This recently submitted test was found to fail on some Cortex-M targets. This was because codegen on these CPUs would emit a ldr instead of a movw/movt pair, resulting in an overall smaller test (i.e. the branch wasn't as far) and the behaviour being tested for not being triggered.

2020-11-30expansion: Improve double-word modulo by certain constant divisors [PR97459]Jakub Jelinek5-1/+337
As discussed in the PR, e.g. on x86_64 (both -m32 and -m64) there is no double-word modulo and so we expand it to a __{,u}mod[dt]i3 call. For certain constant divisors we can do better. E.g. consider 32-bit word-size, 0x100000000ULL % 3 == 1, so we can use partly the Hacker's delight modulo by summing digits approach and optimize unsigned long long foo (unsigned long long x) { return x % 3; } as unsigned long long foo (unsigned long long x) { unsigned int sum, carry; carry = __builtin_add_overflow ((unsigned int) x, (unsigned int) (x >> 32), &sum); sum += carry; return sum % 3; } Similarly, 0x10000000ULL % 5 == 1 (note, 1 << 28), so unsigned long long bar (unsigned long long x) { return x % 5; } as unsigned long long bar (unsigned long long x) { unsigned int sum = x & ((1 << 28) - 1); sum += (x >> 28) & ((1 << 28) - 1); sum += (x >> 56); return sum % 5; } etc. And we can do also signed modulo, long long baz (long long x) { return x % 5; } as long long baz (long long x) { unsigned int sum = x & ((1 << 28) - 1); sum += ((unsigned long long) x >> 28) & ((1 << 28) - 1); sum += ((unsigned long long) x >> 56); /* Sum adjustment for negative x. */ sum += (x >> 63) & 3; unsigned int rem = sum % 5; /* And finally adjust it to the right interval for negative values. */ return (int) (rem + ((x >> 63) & -4)); } 2020-11-30 Jakub Jelinek <jakub@redhat.com> PR rtl-optimization/97459 * internal-fn.h (expand_addsub_overflow): Declare. * internal-fn.c (expand_addsub_overflow): No longer static. * optabs.c (expand_doubleword_mod): New function.

2020-11-30Fix print_multilib_info when default arguments appear in the option list ↵Kito Cheng1-6/+17
with '!' This issue is found when we try to always define MULTILIB_DEFAULTS for -march and -mabi for RISC-V back-end, however `-print-multi-lib` will skip multi-lib setting if match any one of flag in MULTILIB_DEFAULTS, even some options are specified in the option list with '!'. e.g. We have default march=rv32i and mabi=ilp32. And we have following multi-lib set: ". !march=rv32i !march=rv32im !march=rv32imafc !mabi=ilp32 !mabi=ilp32f;" "rv32i/ilp32 march=rv32i !march=rv32im !march=rv32imafc mabi=ilp32 !mabi=ilp32f;" "rv32im/ilp32 !march=rv32i march=rv32im !march=rv32imafc mabi=ilp32 !mabi=ilp32f;" "rv32imafc/ilp32f !march=rv32i !march=rv32ic !march=rv32im march=rv32imafc !mabi=ilp32 mabi=ilp32f;" `-print-multi-lib` willl show `.` and `rv32imafc/ilp32f` only, because the mabi=ilp32 is matched, however there is `!march=rv32i` in `rv32im/ilp32`, so `rv32im/ilp32` should keep, because it reject march=rv32i.

2020-11-29d: Remove d_size_t from front-end sources (PR 87788)Iain Buclaw10-45/+31
The typedef for d_size_t assumes that the implementation of the front-end is written in D itself, where size_t can map only to uint32_t or uint64_t.

2020-11-27libphobos: Fix segfault at run-time when using custom Fibers (PR 98025)Iain Buclaw10-9/+43
When libphobos is configured with --enable-cet, this adds extra fields to the Fiber class to support the ucontext_t fallback implementation. These fields get omitted when compiling user code unless they also used `-fversion=CET' to build their project, which resulted in data being overwritten from within swapcontext(). On reviewing the ucontext_t definitions, it was found that the shadow stack fields were missing, and the struct size didn't match up on X32. This has been fixed in upstream druntime and merged down here.

GIMPLE sequence Also, instead of just examining the first statement of inner 'GIMPLE_BIND' (via 'inner_sequence' being a 'typedef gimple *gimple_seq'), in fact examine all statements contained therein, which I suppose must've been the intention here.

2020-11-27libstdc++: Partially revert r11-5314Jonathan Wakely2-2/+2
The changes in r11-5314 are broken, because it means we don't use __gthread_once for the first few initializations, but after the program becomes multi-threaded we will repeat the initialization, using __gthread_once once this time. This leads to memory errors. The use of __is_single_threaded() in locale::id::_M_id() is OK, because the side effects are the same either way. libstdc++-v3/ChangeLog: * src/c++98/locale.cc (locale::facet::_S_get_c_locale()): Revert change to use __is_single_threaded. * src/c++98/locale_init.cc (locale::_S_initialize()): Likewise.
