[PATCH] options, lto: Optimize streaming of optimization nodes

Hi! When working on the previous patch, I've noticed that all cl_optimization fields appart from strings are streamed with bp_pack_value (..., 64); so we waste quite a lot of space, given that many of the options are just booleans or char options and there are 450-ish of them. Fixed by streaming

[PATCH] arm: Fix up gcc.target/arm/lto/pr96939_* FAIL

Hi! The following patch on top of the https://gcc.gnu.org/pipermail/gcc-patches/2020-September/553801.html patch fixes the gcc.target/arm/lto/pr96939_* test in certain ARM configurations. As said in the above mentioned patch, the generic code takes care of saving/restoring TargetVariables or Targe

[PATCH] arm: Fix up gcc.target/arm/lto/pr96939_* FAIL - alternate version

Hi! The large patch for opts_set saving/restoring doesn't seem to be desirable for backporting (it can be backported and I've even tested it in gcc 10, but it is too large), so this patch instead provides a target only fix. As opts_set can't be trusted, it uses TargetVariables to record whether -m

[PATCH] mixing of labels and code in C2X

Hi Joseph, here is the (unfinished) patch to support mixing of labels in C2X. I preserved existing tests by adding "-std=c17 -pedantic-error" So far, I haven't figured out how to fix the OpenMP related warning in 'gcc.dg/gomp/barrier-2.c'. Best, Martin diff --git a/gcc/c/c-parser.c b/gcc/c/

[PATCH] PR fortran/90903 [part2] Add runtime checking for the MVBITS intrinsic

Dear all, finally here comes the second part of runtime checks for the bit manipulation intrinsics, this time MVBITS. This turned out to be more elaborate than the treatment of simple function calls. I chose the path to inline expand MVBITS, which enables additional optimization opportunities in

[PATCH] Put absolute address jump table in data.rel.ro.local if targets support relocations

Hi,   Jump tables are put into text or rodata section originally. On some platforms, it gains the performance benefit from absolute address jump tables. So I want to let absolute address jump table be relocatable.  This patch puts absolute jump table in read only relocation section if the tar
