<pre>-z notext should allow relocations in a read-only (i.e., the .text) segment,
but lld changes behaviour when -z notext is specified and linking a trivial
application on FreeBSD fails:
% cc -Wl,-z,notext hello.c
/usr/bin/ld: error: relocation R_X86_64_PC32 cannot be used against shared
object; recompile with -fPIC
<span class="quote">>>> defined in /lib/libc.so.7
>>> referenced by crt1.c:63 (/usr/home/emaste/src/freebsd/lib/csu/amd64/crt1.c:63)
>>> /usr/lib/crt1.o:(_start)</span >
cc: error: linker command failed with exit code 1 (use -v to see invocation)
I do not have a reduced test case, but can attach a reproducer for the hello
world link if desired. However, I observe that RelExpr() bypasses the special
case for Sym.isFunc() if !Config->ZText. There's a comment in RelExpr() that
describes this same issue occurring with glibc.</pre>
