| * | | | | | | | | | [dev.power64] 5g,6g,8g: synchronize documentation for regopt structuresAustin Clements2014-11-143-20/+68

Synchronize those comments back in to the other compilers. LGTM=rsc R=rsc CC=golang-codereviews https://codereview.appspot.com/175720043

This ancient artifact was copied from the C compilers, where it was probably necessary to track implicitly used registers. In the Go compilers it's harmless (because it can only over-restrict the set of available registers), but no longer necessary because the Go compilers correctly track register use/set information. The consequences of this extra scan were (at least) that 1) we would not consider allocating the AX register if there was a deferproc call in the future because deferproc uses AX as a return register, so we see the use of AX, but don't track that AX is set by the CALL, and 2) we could not consider allocating the DX register if there was a MUL in the future because MUL implicitly sets DX and (thanks to an abuse of copyu in this code) we would also consider DX used. This commit fixes these problems by nuking this code. LGTM=rsc R=rsc CC=golang-codereviews https://codereview.appspot.com/174110043

| * | | | | | | | | [dev.power64] gc: fix etype of stringsAustin Clements2014-11-064-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The etype of references to strings was being incorrectly set to TINT32 on all platforms. Change it to TSTRING. It seems this doesn't matter for compilation, since x86 uses LEA instructions to load string addresses and arm and power64 disassemble the string into its constituent pieces (with the correct types), but it helps when debugging.

| * | | | | | | | | [dev.power64] 6g: don't create variables for indirect addressesAustin Clements2014-11-051-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, mkvar treated, for example, 0(AX) the same as AX. As a result, a move to an indirect address would be marked as *setting* the register, rather than just using it, resulting in unnecessary register moves. Fix this by not producing variables for indirect addresses. LGTM=rsc R=rsc, dave CC=golang-codereviews https://codereview.appspot.com/164610043
| * | | | | | | | | [dev.power64] gc: convert Bits to a uint64 arrayAustin Clements2014-11-048-109/+119

Power64 has 64 registers, so this converts Bits to a uint64 array so we can continue to use entry 0 directly as a register mask on Power64.

Indeed, excise on power64x failed to preserve the link field, so it excised not only the requested instruction but all following instructions in the function. Fix excise to retain the link field while otherwise zeroing the instruction. This makes nilopt safe on power64x. It still fails nilptr3.go's tests for removal of repeated nil checks because those depend on also optimizing away repeated loads, which doesn't currently happen on power64x.

The cases that handle 1032 bytes and up and 32 bytes and up both use MOVDU (one directly generated in a loop and the other via duffzero), which leaves the pointer register pointing at the *last written* address. The generated code was not accounting for this, so the byte fill loop was re-zeroing the last zeroed dword, rather than the bytes following the last zeroed dword. Fix this by simply adding an additional 8 byte offset to the byte zeroing loop. The case that handled under 32 bytes was also wrong. It didn't update the pointer register at all, so the byte zeroing loop was simply re-zeroing the beginning of region. Again, the fix is to add an offset to the byte zeroing loop to account for this.

Given that, it makes sense to treat labels as function-scoped. This lets each function have its own 'loop' label, for example. Makes the assembly much cleaner and removes the last reason anyone would reach for the 123(PC) form instead. Note that this is on the dev.power64 branch, but it changes all the assemblers. The change will ship in Go 1.5 (perhaps after being ported into the new assembler). Came up as part of CL 167730043.

The argument order was correct in a.y, so just swap the meaning of the arguments in outgcode.
