test.ll
Zig frontend code:
threadlocal var x: i32 = 1234;
pub fn main() void {
x += 1;
}
With LLVM 7.0.0 and LLD 7.0.0, works correctly. With LLVM 8.0.0rc2 and LLD
8.0.0rc2, gives this error:
ld.lld: error: test:(.rodata+0xED): expected R_X86_64_PLT32 or
R_X86_64_GOTPCRELX after R_X86_64_TLSLD
Repro:
clang-8 -o test test.ll -nostdlib memcpy.c -fuse-ld=lld
memcpy.c:
void *memcpy(char *dest, char *src, unsigned n) {
for (unsigned i = 0; i < n; i += 1) {
dest[i] = src[i];
}
return dest;
