Triweekly update from the GHC DevX team at IOG.
Previous updates can be found here.
Sylvain: continued the experimentation with using zig cc/c++ as a C/C++
cross-compiler with GHC to build boot libraries. I manage to cross-build libffi (a
dependency of the RTS) with a libffi fork
that supports Zig's build system.
Sylvain: experimented with the addition of a --target flag to GHC to select a
target. Also added --list-targets to list the available targets. This is not
ready to be upstreamed yet.
stable-GHC#30
Luite: Working on more efficient packing of heap objects by reordering smaller-than-word fields and reducing the size of tag fields of unboxed sums and unpacked constructors.
Sylvain: worked on a fix for the compilation of C files with GHC when no RTS unit is present. GHC#26018, GHC!14300
Sylvain: deprecated an internal module exposed from base.
GHC#23432
CLC!329
