Bug ID: 29093
Summary: version script does not support [chars] wildcards
Product: lld
Version: unspecified
Hardware: PC
OS: FreeBSD
Status: NEW
Severity: normal
Priority: P
Component: ELF
Assignee: unassignedb...@nondot.org
Reporter: ema...@freebsd.org
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
GNU ld supports [chars] wildcards in version scripts, to match a single
instance of any of the chars. I encountered this on FreeBSD building GNU
libstdc++ (which is not used in the base system on x86-64, but is on MIPS). A -
may be used to specify a range of characters (e.g. [a-z]) and ^ inverts the
sense (so any character not in the set, e.g. [^a-z]).
Here is an excerpt from libstdc++'s version script in FreeBSD:
extern "C++"
{
...
std::locale::_[T-Za-z]*;
# std::[A-Zm-r]*;
std::[A-Zm]*;
std::n[^u]*;
std::nu[^m]*;
std::num[^e]*;
...
}
