Things are a little better. The LLD that comes with Linux seems to work.
Old versions like LLVM 8 haven't been supported since Cosmopolitan v0.2.
Running Clang on Windows with --target=x86_64-pc-linux-gnu doesn't seem
to work. It has something to do with the recently added .zip section in
the linker script. But even if that's removed, LLD on Windows thinks it
is building an EFI application for some reason. Linker scripts are such
a brittle house of cards, even for just ld.bfd alone..
We should just find a way to run our one true musl-cross-make linux gcc
toolchain under Blinkenlights on non-Linux because GCC and Clang are so
nondeterministic, inconsistent, and unreproducible when built for other
operating systems. We need an actually portable compiler/linker that'll
always behave the same way no matter what.
See #180
You can now build Cosmopolitan with Clang:
make -j8 MODE=llvm
o/llvm/examples/hello.com
The assembler and linker code is now friendly to LLVM too.
So it's not needed to configure Clang to use binutils under
the hood. If you love LLVM then you can now use pure LLVM.
It turned out that the linker was doing the wrong with the amalgamation
library concerning weak stubs. A regression test has been added and new
binaries have been uploaded to https://justine.lol/cosmopolitan/
Ideally this should be fixed by building a tool that turns multiple .a
files into a single .a file with deduplication. As a workaround for now
the cosmopolitan.a build is restructured to not include LIBC_STUBS which
meant technical debt needed to be paid off where non-stub interfaces
were moved to LIBC_INTRIN and LIBC_NEXGEN32E.
Thank @PerfectProductions in #31 for the report!
