2017-06-13[ARM][Testsuite]make dump_stack function call conditional in cold-lc.cRenlin Li2-3/+9
After r249013, die () and dump_stack () are both in cold section. This makes the compiler generate bl instruction for the function call, instead of honoring the -mlong-calls option. This patch changes the dump_stack function call conditional, which fixes the regression. gcc/testsuite/ * gcc.target/arm/cold-lc.c: Update coding style, call dump_stack conditionally.

2017-06-12runtime: ignore _Gscan bit when checking status in CgocallDoneIan Lance Taylor1-1/+1
Also always access the atomicstatus field atomically. The effect of not checking the _Gscan bit is that if the GC decides to scan the stack just as the goroutine is leaving the system call, the goroutine might fail to call exitsyscall. Then then typically causes a runtime assertion failure later on. If we do call exitsyscall as we should, it will stall (in casgstatus) until the _Gscan bit is cleared. No separate test. I've observed causing sporadic failures running the misc/cgo tests, but we don't currently have a way to run those routinely for gccgo. I should fix that.
