[PATCH] PR fortran/71706 - [8/9/10/11 Regression] [Coarray] ICE on using sync images with integer(kind<>4), with -fcoarray=lib -fcheck=bounds

Here's a fix to bounds-checking code that manifests itself essentially with checking enabled. Once found and understood, the fix is trivial: just properly convert the argument kind of SYNC IMAGES for checking. Regtested on x86_64-pc-linux-gnu. OK for master / backports where appropriate?

[committed] d: Merge upstream dmd 8508c4e68.

Hi, This patch merges the D front-end implementation with upstream dmd 8508c4e68. Fixes a performance bug where 'static foreach' would take an exponentially long time to expand during CTFE. In the following example: static foreach (i; 0..3) {} Compilation time had been reduced from

Enable FMA in rsqrt2 expander and fold rsqrtv16sf2 expander into rsqrt2 expander which expands to UNSPEC_RSQRT28 for TARGET_AVX512ER. Although it doesn't show performance change in our workloads, FMA can improve other workloads. gcc/ PR target/88713 * config/i386/i386-expand.c

Hi, We need to skip past namespace decls when scanning the bind expression var lists checking for local vars. The PR notes that this omission results in an ice-on-valid. tested on x86_64-linux, darwin, powerpc64-linux, applied to master as obvious (and will backport to 10.2). thanks Iain

Hi Harald, A rather straightforward issue (mis-)referencing the proper symbol name in an error message. OK for master / backport? OK, but don't forget the test case :-) Because the if takes up quite a few lines, it is also an option to write something like gfc_error ("Symbol %qs at %L
