Re: [Patch] Fortran: OpenMP fix declare simd inside modules and absent linear step [PR106566]

Fixed subject line: "absent linear" should be "absent linear step" in the subject line; i.e. with "step" added: "Fortran: OpenMP fix declare simd inside modules and absent linear step [PR106566]" I have also decided to move the 'step = 1' to openmp.cc, which also set it before with the old pre

[Patch] OpenMP: Fix var replacement with 'simd' and linear-step vars [PR106548]

The testcase is just a copy of linear-1 with 'omp ... for' replaced by 'omp ... for simd', matching what the PR report referred to. The problem occurs for 'omp ... for simd linear( i : step)' when 'step' is a variable when a omp_fn... is generated - as in this case, the original variable is use

[PATCH] bug in emergency cxa pool free()

This probably has never actually affected anyone in practice. The normal ABI implementation just uses malloc and only falls back to the pool on malloc failure. But if that happens a bunch of times the freelist gets out of order which violates some of the invariants of the freelist (as well as the c

[PATCH] d: Fix #error You must define PREFERRED_DEBUGGING_TYPE if DWARF is not supported (PR105659)

Hi, Because targetdm contains hooks pertaining to both the target platform and cpu, it tries to pull in both platform and cpu headers via tm_d.h in the source file where TARGETDM_INITIALIZER is used. Since 12.0, this has caused problems when there is no platform (*-elf), resulting in default-d.cc
