Bug ID: 17640
Summary: [i386] Convert load to lea
Product: binutils
Version: 2.26 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: gold
Assignee: ccoutant at google dot com

For i386, we should convert
mov foo@GOT(%reg), %reg
to
lea foo@GOTOFF(%reg), %reg
if foo is a local symbol. This is the result from ld:
[hjl@gnu-6 lea-1]$ cat lea2.s
.text
.type foo, @function
foo:
ret
.size foo, .-foo
.globl bar
.type bar, @function
bar:
movl foo@GOT(%ecx), %eax
.size bar, .-bar
[hjl@gnu-6 lea-1]$ gcc -c -m32 lea2.s
[hjl@gnu-6 lea-1]$ ld -m elf_i386 -shared lea2.o
[hjl@gnu-6 lea-1]$ objdump -dw a.out
a.out: file format elf32-i386
Disassembly of section .text:
00000129 <foo>:
129: c3 ret
0000012a <bar>:
12a: 8d 81 a1 ef ff ff lea -0x105f(%ecx),%eax
[hjl@gnu-6 lea-1]$
