Bug ID: 237676
Summary: [Minor] LLD Filesize and default option suggestions
Product: Base System
Version: 12.0-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: [email protected]
Reporter: [email protected]
The .comment section added by lld should be removed and made optional.
The file size using lld is unacceptable (some still use assembly) for embedded
stuff. The default is 1200% larger by default and should be minimal like gnu
ld.
# /usr/local/bin/ld -s -o porcupine porcupine.o
# ld --discard-all -o porcupine.lld -m elf_amd64_fbsd porcupine.o
# strip porcupine.lld
# objcopy --remove-section .comment porcupine.lld
# ls -l porcupine porcupine.lld
-rwxr-xr-x 1 root wheel 352 Apr 30 23:41 porcupine
-rwxr-xr-x 1 root wheel 4320 Apr 30 23:41 porcupine.lld
Specifying `-m elf_amd64_fbsd` or similar shouldn't be necessary and should be
the default (depending on platform).
