Subject: [SDK] How to use the gold linker
Date: Mon, 14 Dec 2020 12:14:18 +0100 [thread overview]
Message-ID: <5776519.IOBmFsySL6@n95hx1g2> (raw)
Branch: dunfell
Arch: arm
When I set -fuse-ld=gold with the Yocto SDK, the bfd linker is used anyway:
> . /opt/poky-tiny/3.1.4/environment-setup-cortexa7t2hf-neon-vfpv4-poky-linux-musleabi
> ${CC} -fuse-ld=gold -Wl,--threads -o test test.c
/opt/poky-tiny/3.1.4/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/9.3.0/real-ld: unrecognized option '--threads'
/opt/poky-tiny/3.1.4/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/9.3.0/real-ld: use the --help option for usage information
When I call the "real-ld" with -h, I can see that it's the BFD linker.
> ${CC} -print-prog-name=ld
/opt/poky-tiny/3.1.4/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/9.3.0/ld
> ${CC} -fuse-ld=bfd -print-prog-name=ld
ld.bfd
> ${CC} -fuse-ld=gold -print-prog-name=ld
ld.gold
Compared to other cross toolchains I use, the output of the previous two commands
miss the full path to the linker. The gold linker is part of my SDK:
> arm-poky-linux-musleabi-ld.gold --help
Usage: arm-poky-linux-musleabi-ld.gold [options] file...
Options:
--help Report usage information
...
How can I use the gold linker from gcc (without making it default)?
regards
Christian
