[PATCH 0/4] target/mips: Rewrite UHI errno_mips() to allow building on Haiku OS

Posted by Philippe Mathieu-Daudé 4 years, 7 months ago

Richard Zak reported a build failure on Haiku OS which is due
to using POSIX errno as array indexes:
https://www.mail-archive.com/qemu-devel@nongnu.org/msg820587.html

Work around by using a GHashTable.

Since we were reviewing the UHI (semihosting) spec, fix the errno
values and complete to support all the specified errnos.

Regards,

Phil.
