gold accepts quoted strings. binutils requires quoted strings for some
kinds of symbols, e.g.:
it accepts quoted symbols with @ in name:
$ echo 'EXTERN("__libc_start_main@@GLIBC_2.2.5")' > a.script
$ g++ a.script
/usr/lib/gcc/x86_64-redhat-linux/4.8.5/../../../../lib64/crt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
collect2: error: ld returned 1 exit status
but rejects them if unquoted:
$ echo 'EXTERN(__libc_start_main@@GLIBC_2.2.5)' > a.script
$ g++ a.script
a.script: file not recognized: File format not recognized
collect2: error: ld returned 1 exit status
To maintain compatibility with existing linker scripts support quoted
strings in lld as well.
