Bug ID: 22791
Summary: Don't error when a -pie executable uses a shared
function without a got
Product: binutils
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gold
Assignee: ccoutant at gmail dot com
Reporter: rafael.espindola at gmail dot com
CC: ian at airs dot com
Target Milestone: ---
The following testcase fails with gold
$ cat test.s
.globl _start
_start:
callq vcall
$ cat test2.s
.global vcall
.type vcall,@function
vcall:
nop
$ ld.gold test2.o -o test2.so -shared
$ ld.gold test.o test2.so -o t -pie
ld.gold: error: test.o: requires dynamic R_X86_64_PC32 reloc against 'vcall'
which may overflow at runtime; recompile with -fPIC
But there is no reason why trick of defining a symbol pointing to the plt entry
would not work with a PIE.
Starting with c5bb8910e80c6cd80c63541f86471c18375c8198 bfd uses TEXTREL, but
that seems less desirable than creating a symbol pointing to the plt entry as
is done in the non -pie case.
