Hadrian: Build fails if StgRun/Return are implemented in asm file
Summary
Hadrian fails to build if StgRun
and StgReturn
are implemented in assembler file rts/StgCRunAsm.S
rather than in C file rts/StgCRun.c
:
$ ./hadrian/build.sh
[...]

Call hs_init_ghc() from your main() function to set these options.

Steps to reproduce
Just move both functions from the C file to the S file of your favourite architecture. Then in file rts/rts.cabal.in
add your favourite architecture to the if
condition for asm-sources: StgCRunAsm.S
and run hadrian.
Are there other places in which the assembler file must be registered for an particular architecture? Did I miss something?
