b8fb52446c Cranelift: implement redundant fill removal on tree-shaped CFG regions. Mozilla bug 1570584. (#906) 2019-08-25 19:37:34 +02:00

cc57e84cbd Fix segfault due to b64 encoding (#919) 
* Fix segfault due to b64 encoding

Prior to this patch, bconst.b64 encoded its instruction with a 32-bit immediate that caused improper decoding of the MOV instruction; instead, use a REX prefix and rely on zero-extension of the immediate. Fixes #911.

b4ef90cfcd Remove SSE2 setting for x86 
In talking to @sunfishcode, he preferred to avoid the confusion of more ISA predicates by eliminating SSE2. SSE2 was released with the Pentium 4 in 2000 so it is unlikely that current CPUs would have SIMD enabled and not have this feature. I tried to note the SSE2-specific instructions with comments in the code.

d492cf7e0e Avoid unnecessary lane calculations in codegen code 
This refactor moves the calculation of the number of lanes to code closer to where the Instruction/BoundInstruction is bound.

627ba24b59 Simplify jump table instructions and add missing conversion; 
This makes non-legalized jump table instructions operate on operands with
pointer-sized types. This means we need to extend smaller types into the
pointer-sized operand, when the two don't match.

d9277f249b [meta] Introduce the InstructionGroupBuilder; 
This follows the rest of the code base data structures, where we have a
mutable data structure builder; once the data structure is constructed,
it's immutable.

This also makes the definition of instructions easier, and it paves the
way for defining immediate variants.
