* Reduce the likelihood of x64/x86-64 changes breaking the build on other ↵Erik de Castro Lopo2012-08-211-36/+20
| | | | | | | | | | | | | | arches (#7083). Code that needs to differentiate between i386 and x86-64 should now be written as if x86-64 is the default and i386 is the special case. Eg: # if i386_TARGET_ARCH someFuncion = ..... # else someFuncion = ..... # endif
* Fix build failure on OS X (#7119)Simon Marlow2012-08-091-1/+2
| | | | | When refactoring this recently I accidentally put the dead-strip-preventer symbol (only used on OS X) in the wrong section.

| * Disable the mini-inliner when using the new codegenSimon Marlow2012-08-021-1/+4
| | | | | | | | | | The new sinker is at least as powerful, and the mini-inliner sometimes even makes things worse.
| * Improve code generated when real registers are clobberedSimon Marlow2012-07-311-32/+59
| | | | | | | | | | | | | | | | There was a long-standing ToDo here that I just did: if a real register is clobbered by the current instruction, then we should move it to another free register rather than spilling it to memory. This case crops up more often now that the register allocator can allocate into the fixed Rn registers.

| * New codegen: do not split proc-points when using the NCGSimon Marlow2012-07-306-143/+157
| | | | | | | | | | | | | | | | | | Proc-point splitting is only required by backends that do not support having proc-points within a code block (that is, everything except the native backend, i.e. LLVM and C). Not doing proc-point splitting saves some compilation time, and might produce slightly better code in some cases.
| * bugfix: cope when a source reg is dead at a join pointSimon Marlow2012-07-301-10/+4
| | | | | | | | | | We didn't trip over this one until I started generating code without proc-point splitting, which has more join points and loops.

* Don't re-allocate %esi on x86.Simon Marlow2012-07-091-0/+17
| | | | | | | | | | | | | Recent changes have freed up %esi for general use on x86 when it is not being used for R1. However, x86 has a non-uniform register architecture where there is no 8-bit equivalent of %esi. The register allocators aren't sophisticated enough to cope with this, so we have to back off and treat %esi as non-allocatable for now. (of course, LLVM doesn't suffer from this problem) One workaround would be to change the calling convention to use %rbx for R1, however we can't change the calling convention now without patching LLVM too.

* Allow the register allocator access to argument regs (R1.., F1.., etc.)Simon Marlow2012-07-065-81/+61
| | | | | | | | | | | | | | | This was made possible by the recent change to codeGen to attach the live GlobalRegs to every CmmJump, and we'll be relying on it quite heavily in the new code generator too. What this means essentially is that when we see x = R1 the register allocator will automatically assign x to R1 and generate no code at all (also known as "coalescing"). It wasn't possible before because the register allocator had to assume that R1 was always live, because it didn't have access to accurate liveness information.
