Bug ID: 34719
Summary: Build broken with glibc 2.26 on AArch64
Product: compiler-rt
Version: 4.0
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: compiler-rt
Assignee: unassignedbugs at nondot.org
Reporter: tstellar at redhat.com
CC: llvm-bugs at lists.llvm.org
This glibc commit[1] renamed the __reserved field from the m_context struct to
__glibc_reserved1,
which is causing build failure on aarch64:
lib/sanitizer_common/sanitizer_linux.cc: In function 'bool
__sanitizer::Aarch64GetESR(ucontext_t*, __sanitizer::u64*)':
lib/sanitizer_common/sanitizer_linux.cc:1268:35: error: 'struct mcontext_t' has
no member named '__reserved'; did you mean '__glibc_reserved1'?
u8 *aux = ucontext->uc_mcontext.__reserved;
^~~~~~~~~~
__glibc_reserved1
I have not tested trunk yet, but just from looking at the source code, it looks
like trunk compiler-rt will fail to compile too.
