Bug ID: 71929
Summary: libcilkrts build failure because broken
__cilkrts_yield and __cilkrts_idle
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: nsz at gcc dot gnu.org
Target Milestone: ---
os-unix.c is broken on *linux-musl targets.
the portable way to yield is sched_yield, this should be called on all
platforms including linux, except on systems where it does not exist (only
__MIC__).
pthread_yield should not be called on *linux-gnu either.
sched_yield is declared in sched.h so it should be included on all targets.
../../../src_toolchain/libcilkrts/runtime/os-unix.c: In function
'__cilkrts_yield':
../../../src_toolchain/libcilkrts/runtime/os-unix.c:471:5: warning: implicit
declaration of function 'pthread_yield'; did you mean 'pthread_self'?
[-Wimplicit-function-declaration]
pthread_yield();
