It appears that generation of TLS_LDO_HIX22 relocation for sparc is broken.
Reduced testcase:
] cat tls-hix.cc
static thread_local void* StackTraceHead = nullptr;
void* foo() {
return StackTraceHead;
}
int main() {
return !foo();
}
] bin/clang++ tls-hix.cc -std=c++11 -m64
ld: fatal: relocation error: R_SPARC_TLS_LE_HIX22: file
/var/tmp/tls-hix-548455.o: symbol _ZL14StackTraceHead: value 0x3fffffffc00001
does not fit
clang-5.0: error: linker command failed with exit code 1 (use -v to see
