<pre>In musl-1.1.10 and foward, musl provides rcrt1 in addition to crt{1,i,n}. This
new crt start file, rcrt1.o, is provided for producing static-linked position
independent executables (PIE). [1]
rcrt1.o is a dependency of musl, and musl will not compile unless it is able to
access the __dls2 function that is defined in it.
GNU linkers such as bfd and gold have added support for including this file,
and musl compiles with no issue. But when I tried to use lld as a drop in
replacement, the build fails, and the lld throws this error:
/usr/bin/x86_64-gentoo-linux-musl-ld: error: undefined symbol: __dls2
<span class="quote">>>> referenced by ld-temp.o
>>> lto.tmp:(_dlstart_c)</span >
clang-5.0: error: linker command failed with exit code 1 (use -v to see
invocation)
A couple grep -R's in lld's source code didn't reveal anything concerning
rcrt1, so I am assuming it has not been implemented yet.
lld version is 5.0.1
