[Bug gold/24415] New: - -Wl,--wrap= incompatible with -flto
https://sourceware.org/bugzilla/show_bug.cgi?id=24415
Bug ID: 24415
Summary: - -Wl,--wrap= incompatible with -flto
Product: binutils
Version: 2.33 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gold
Assignee: ccoutant at gmail dot com
Reporter: dilyan.palauzov at aegee dot org
CC: ian at airs dot com
Target Milestone: ---
This is t.c:
---
#include
#include
ssize_t __wrap_read(int fd, void *buffer, size_t count) {
printf("%s\n", (char*)buffer);
return fd + count;
}
int main() {
int i = read(1, "abc", 5);
printf("%i\n", i);
}

I have gcc 8.3.1 20190331, clang 8.0.0, lld 8.0.0, ld.bfd 2.32.51.20190401 with
the patch from https://sourceware.org/ml/binutils/2019-04/msg00011.html, and
ld.gold (GNU Binutils 2.32.51.20190319) 1.16.
This works (compiles and links):
clang t.c -Wl,--wrap=read -O3 -fuse-ld=lld -flto
clang t.c -Wl,--wrap=read -O2 -fuse-ld=lld -flto
clang t.c -Wl,--wrap=read -O1 -fuse-ld=lld -flto
clang t.c -Wl,--wrap=read -O1 -fuse-ld=bfd -flto
clang t.c -Wl,--wrap=read -O2 -fuse-ld=bfd -flto
clang t.c -Wl,--wrap=read -O3 -fuse-ld=bfd -flto
clang t.c -Wl,--wrap=read -O3 -fuse-ld=gold -flto
clang t.c -Wl,--wrap=read -O2 -fuse-ld=gold -flto
clang t.c -Wl,--wrap=read -O1 -fuse-ld=gold -flto
gcc t.c -Wl,--wrap=read -O3 -fuse-ld=bfd -flto
gcc t.c -Wl,--wrap=read -O2 -fuse-ld=bfd -flto
gcc t.c -Wl,--wrap=read -O1 -fuse-ld=bfd -flto
This does not work (does not link):
gcc t.c -Wl,--wrap=read -O1 -fuse-ld=gold -flto
gcc t.c -Wl,--wrap=read -O2 -fuse-ld=gold -flto
gcc t.c -Wl,--wrap=read -O3 -fuse-ld=gold -flto
