tests/tcg: enable building for sh4 As before, using Debian SID compilers. While the compiler can be coerced into generating big-endian code it seems the linker can't deal with it so we only enable the building for little endian SH4.

tests/tcg/multiarch: Re-enable signals test for most guests With signal trampolines safely off the stack for all guests besides hppa, we can re-enable this test. It does show up a problem with sh4 (unrelated?), so leave that test disabled for now.

target/sh4: Fix mac.l with saturation enabled The saturation arithmetic logic in helper_macl is not correct. I tested and verified this behavior on a SH7091.

target/sh4: Fix ADDV opcode The documentation says: ADDV Rm, Rn Rn + Rm -> Rn, overflow -> T But QEMU implementation was: ADDV Rm, Rn Rn + Rm -> Rm, overflow -> T Fix by filling the correct Rm register.

target/sh4: Fix SUBV opcode The documentation says: SUBV Rm, Rn Rn - Rm -> Rn, underflow -> T The overflow / underflow can be calculated as: T = ((Rn ^ Rm) & (Result ^ Rn)) >> 31 However we were using the incorrect: T = ((Rn ^ Rm) & (Result ^ Rm)) >> 31 Fix by using the Rn register instead of Rm.
