Bug ID: 30797
Summary: clear_cache doesn't compile in Debug mode
Product: compiler-rt
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: compiler-rt
Assignee: unassignedb...@nondot.org
Reporter: renato.go...@linaro.org
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
clear_cache.c fails to build on ARM in debug mode because of the line:
const register int syscall_nr __asm("r7") = __ARM_NR_cacheflush;
with the error:
error: r7 cannot be used in asm here
It passes on Release mode because -O2/3 implies -fmoit-frame-pointer.
