Bug ID: 98063
Summary: Emit R_X86_64_GOTOFF64 instead of R_X86_64_GOTPCRELX
for -mcmodel=large -fno-plt
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: i at maskray dot me
Target Milestone: ---
% cat a.c
#include <stdio.h>
int main() {
puts("meow");
}
% gcc -mcmodel=large -fno-plt -O1 -S a.c -fpic -o - -O2
-fno-asynchronous-unwind-tables
...
main:
.L2:
movabsq $_GLOBAL_OFFSET_TABLE_-.L2, %r11
subq $8, %rsp
leaq .L2(%rip), %rax
movabsq $.LC0@GOTOFF, %rdx
addq %r11, %rax
leaq (%rax,%rdx), %rdi
call *puts@GOTPCREL(%rip)
xorl %eax, %eax
addq $8, %rsp
ret
The distance between the GOT entry and the next instruction of call may be
larger than 32-bit. An R_X86_64_GOTPCRELX relocation cannot be used.
