Compiler Fixes
This release:
- Adds GS, WH & BH multilibs. This enables GS and WH workarounds for some chip errata.
- Adds QEMU test infrastructure, augmented build scripts and GCC testsuite.
- Fixes several internal compiler errors when checking is enabled.
- One outcome of those changes is that the
rvtt_l1_ptr
andrvtt_reg_ptr
consistently create distinct types, and thus previously unreported type mismatch errors may occur. (Previously these attributes had inconsistent behavior regarding the distinctness of types.)
