When compiling gcc.dg/vla-1.c with -O3 -g, vla a and b in f1 are optimized
away, and f1 is cloned to a version f1.constprop with no parameters, eliminating
parameter i. Debug info is generated to describe the sizes of a and b, but
that process generates debug expressions that are not reused.
Fix the duplication by saving and reusing the generated debug expressions in
remap_ssa_name. Concretely: reuse D#7 here instead of generating D#8:
...
__attribute__((noinline))
f1.constprop ()

Optimization fipa-icf breaks debug info (as is noted in PR63572 - "ICF breaks user debugging experience"), which make guality tests clztest.c, ctztest.c and sra-1.c unsupported for option combination "-O2 -flto -fuse-linker-plugin -fno-fat-lto-objects". F.i., in clztest.c foo and bar are merged, and gdb can set a breakpoint on a line in foo, but trying to set a breakpoint on a line in bar results in a breakpoint in main instead.

This patch moves the vendor and CPU id data from driver-arm.c to the main table of CPU data in arm-cpus.in. It then adds rules to parsecpu.awk to build data tables that can be used by the driver for automatic CPU detection when running natively. This is the last major bit of CPU-specific data that can be usefully moved to the CPU data tables (I don't think it is sensible to move the per-cpu tuning data from its current location). The syntax and parser can support revision ranges, but at present nothing is done with that data: no supported cpu currently needs that capability. * config/arm/driver-arm.c: Include arm-native.h.

C. for strcmp (s1, s2), strncmp (s1, s2, n), and memcmp (s1, s2, n) if the result is NOT used to do simple equality test against zero, one of "s1" or "s2" is a small constant string, n is a constant, and the Min value of the length of the constant string and "n" is smaller than a predefined threshold T, inline the call by a byte-to-byte comparision sequence to avoid calling overhead. adding test case strcmpopt_5.c into gcc.dg for part C of PR78809. adding test case strcmpopt_6.c into gcc.dg to test the following case: When the specified length exceeds one of the arguments of the call to memcmp, the call to memcmp should NOT be inlined. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@262636 138bc75d-0d04-0410-961f-82ee72b054a4

The frontend could parse omitted pointer typess at the end of the

r259399, which added PROCESSOR_SKYLAKE, disabled many x86 optimizations
which are enabled by PROCESSOR_HASWELL. As the result, -mtune=skylake
generates slower codes on Skylake than before. The same also applies
to Cannonlake and Icelak tuning.
This patch changes -mtune={skylake|cannonlake|icelake} to tune like
-mtune=haswell for until their tuning is properly adjusted. It also
enables -mprefer-vector-width=256 for -mtune=haswell, which has no
impact on codegen when AVX512 isn't enabled.

The libffi library doesn't understand zero-sized objects.
When we see a zero-sized field in a struct, just skip it when
converting to the FFI data structures. There is no value to pass in
any case, so not telling libffi about the field doesn't affect
anything.
The test case for this is https://golang.org/cl/123316.

An rl<wd>imi instruction is often written like "(a << 8) | (b & 255)". If "b" now is a byte in memory, combine will combine the load with the masking (with 255 in the example), since that is a single instruction; and then the rl*imi isn't combined from the remaining pieces.

There are various ways that it's possible for a gimple statement to have an UNKNOWN_LOCATION, and for that UNKNOWN_LOCATION to be wrapped in an ad-hoc location to capture inlining information. For such a location, LOCATION_FILE (loc) is NULL. Various places in -fsave-optimization-record were checking for loc != UNKNOWN_LOCATION and were passing LOCATION_FILE (loc) to code that assumed a non-NULL filename, thus leading to segfaults for the above cases. This patch updates the tests to use LOCATION_LOCUS (loc) != UNKNOWN_LOCATION instead, to look through ad-hoc location wrappers, fixing the segfaults. It also adds various assertions to the affected code. gcc/ChangeLog: PR tree-optimization/86636 * json.cc (json::object::set): Fix comment. Add assertions.

This is missing the synchronized_pool_resource and unsynchronized_pool_resource classes but is otherwise complete. This is a new implementation, not based on the existing code in <experimental/memory_resource>, but memory_resource and polymorphic_allocator ended up looking almost the same anyway. The constant_init kluge in src/c++17/memory_resource.cc is apparently due to Richard Smith and ensures that the objects are constructed during constant initialiation phase and not destroyed (because the constant_init destructor doesn't destroy the union member and the storage is not reused). * config/abi/pre/gnu.ver: Export new symbols. * configure: Regenerate. * include/Makefile.am: Add new <memory_resource> header. * include/Makefile.in: Regenerate. * include/precompiled/stdc++.h: Include <memory_resource> for C++17. * include/std/memory_resource: New header.
