Matt Arsenault 2398c72d1f Mips/GlobalISel: Use more standard call lowering infrastructure ... This also fixes some missing implicit uses on call instructions, adds missing G_ASSERT_SEXT/ZEXT annotations, and some missing outgoing sext/zexts. This also fixes not respecting tablegen requested type promotions. This starts treating f64 passed in i32 GPRs as a type of custom assignment, which restores some previously XFAILed tests. This is due to getNumRegistersForCallingConv returns a static value, but in this case it is context dependent on other arguments. Most of the ugliness is reproducing a hack CC_MipsO32 uses in SelectionDAG. CC_MipsO32 depends on a bunch of vectors populated from the original IR argument types in MipsCCState. The way this ends up working in GlobalISel is it only ends up inspecting the most recently added vector element. I'm pretty sure there are cleaner ways to do this, but this seemed easier than fixing up the current DAG handling. This is another case where it would be easier of the CCAssignFns were passed the original type instead of only the pre-legalized ones. There's still a lot of junk here that shouldn't be necessary. This also likely breaks big endian handling, but it wasn't complete/tested anyway since the IRTranslator gives up on big endian targets.		2021-07-13 11:04:10 -04:00
