Go patch committed: Fix length of roots array

This patch by Than McIntosh fixes the length of the type of the roots array in Gogo::register_gc_vars. Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu. Committed to mainline. Ian Index: gcc/go/gofrontend/MERGE === ---

[Committed] Lower iterator count on gcc.dg/atomic/c11-atomic-exec-5.c for AARCH64

Since AARCH64 does not have a native 128bit atomics, this testcase can take a long time with the default iteration count on a "fast" multi-core machine. This is because the thread which incrementing the counter is not able to acquire the mutex before the other thread has already acquired it. I

[PATCH/AARCH64] Add -mcpu=thunderx2t99 support

Hi, This patch adds -mcpu=thunderx2t99. Cavium has acquired the Vulcan IP from Broadcom. I am keeping the old -mcpu=vulcan as backwards compatible but renaming all of the structures to be based on the new name of the chip. In the next few weeks, I am auditing the current tuning and will be

[PATCH], PR 71977/70568/78823: Improve PowerPC code that uses SFmode in unions

This is both a fix to a regression (since GCC 4.9), a code improvement for GLIBC, and fixes potential bugs with the recent changes to allow small integers (32-bit integer, SImode in particular) in floating point and vector registers. The core of the problem is when a SFmode (32-bit binary

[PATCH, i386]: Remove unneeded *extvqi sign-extract pattern

Hello! Attached patch removes unneeded *extvqi sign-extract pattern. Combine is smart enough to create zero-extract RTX in case QImode value is extracted to QImode register. OTOH, the following testcase --cut here-- struct S1 { char pad1; char val; short pad2; }; struct S1 test_add
