  • 81bc2c74c5 A bb's regsin are no longer the same as those of its first instruction; occasionally the first hop of a block would try to rearrange its registers (due to evicted throughs), resulting in the phi moves copying values into the wrong registers. David Given 2016-11-16 20:52:15 +01:00

  • e7132183fb Fix buffer overrun: if LABEL_STARTER is seen but LABEL_TERMINATOR is not, the label parser will keep going forever looking for the end of the label. It now stops at the end of the string. David Given 2016-11-13 14:04:58 +01:00
  • 6a4f465f53 Add a rather bodged test framework for the qemuppc plat, which only runs if the qemu-system-ppc emulator is installed. David Given 2016-11-13 13:37:22 +01:00
  • e9fe1d70a6 Fix (or at least, work around) an issue with library order. Make sure the Basic error symbols are actually defined. David Given 2016-11-13 13:28:09 +01:00

  • 48e74f46fc Add the very experimental qemuppc plat, intended to generate minimal images which can be emulated using qemu (for, hopefully, a test suite). Currently it generates images which won't run because there's no RAM. David Given 2016-11-12 19:20:58 +01:00

  • 852d3a691d Update the table to return call output values in the right registers. Fix the register allocator so the corrupted registers only apply to throughs (otherwise, you can't put output registers in corrupted registers). David Given 2016-11-11 21:48:36 +01:00
  • b5c1d622f5 Rework the way stack frames are laid out to be simpler and, hopefully, more correct. Saved registers are now placed in what may be the right place. David Given 2016-11-11 21:17:45 +01:00

  • 61349389fb More opcodes. sti can now cope with non-standard sizes (really need a better fix for this). Hack in crude support for mismatched stack pushes and pops (ints vs longs). David Given 2016-10-29 12:48:05 +02:00
  • 68419da235 Actually, the locals need to go above the spills and saved regs, so fp == lb. David Given 2016-10-29 12:00:33 +02:00
  • 2cc2c0ae98 Lots more opcodes. Rearrange the stack layout so that fp->ab is a fixed value (needed for CHAINFP and FPTOAB). Wire up lfrs to calls via a phi when necessary, to allow call-bra-lfr chains. David Given 2016-10-29 11:57:56 +02:00
