OK. Just to confirm, what do you see from
objdump -dr
./tools/gollvm/libgo/CMakeFiles/libgo_c_piclib.dir/__/gofrontend/libgo/go/syscall/errno.c.o
for the prolog of syscall.Geterrno. Should be something like
Disassembly of section .text.syscall.GetErrno:
0000000000000000 <syscall.GetErrno>:
0: 64 48 3b 24 25 70 00 cmp %fs:0x70,%rsp
7: 00 00
9: 72 11 jb 1c <syscall.GetErrno+0x1c>
b: 48 83 ec 08 sub $0x8,%rsp
f: e8 00 00 00 00 callq 14 <syscall.GetErrno+0x14>
10: R_X86_64_PLT32 __errno_location-0x4
Thanks, Than
?
