Trevor Elliott	b077854b57	Generate SSA code from returns (#5172) ... Modify return pseudo-instructions to have pairs of registers: virtual and real. This allows us to constrain the virtual registers to the real ones specified by the abi, instead of directly emitting moves to those real registers.	2022-11-08 16:00:49 -08:00
Trevor Elliott	02620441c3	Add uadd_overflow_trap (#5123) ... Add a new instruction uadd_overflow_trap, which is a fused version of iadd_ifcout and trapif. Adding this instruction removes a dependency on the iflags type, and would allow us to move closer to removing it entirely. The instruction is defined for the i32 and i64 types only, and is currently only used in the legalization of heap_addr.	2022-10-27 09:43:15 -07:00
