CROSS_EMULATOR convention needs proper documentation
!9515 (merged) landed preliminary support for using a cross emulator to run target executables when testing a cross GHC. However, it's completely undocumented, and some questions needs more thinking:
-
CROSS_EMULATOR
is currently just an environment variable picked up byhadrian test
. Should it be a part of theconfigure
process? - The testsuite driver's cpu feature detection currently doesn't interact with it. IMO host cpu feature set doesn't make a lot of sense when testing a cross GHC.
