[Qemu-devel] [PATCH, RFC 00/18] Use stack frame for TCG temporaries

[Blue Swirl]

This patch series is still RFC. Updated versions of x86_64 and i386
seems to work, Sparc64 is not changed since previous version.

I've added code for other targets too, but those parts are not even
compile tested, so review is necessary.

It would be possible to commit just the working patches, maybe also
TCG_REG_CALL_STACK renames (which could be combined). Opinions here
also welcome.

Blue Swirl (18):
  Delegate setup of TCG temporaries to targets
  TCG: fix negative frame offset calculations
  TCG: remove broken stack allocation for call arguments
  TCG/x86: use TCG_REG_CALL_STACK instead of TCG_REG_ESP
  TCG/x86: use stack for TCG temps
  TCG/Sparc64: use stack for TCG temps
  TCG/ARM: use stack for TCG temps
  TCG/HPPA: use TCG_REG_CALL_STACK instead of TCG_REG_SP
  TCG/HPPA: use stack for TCG temps
  TCG/IA64: use TCG_REG_CALL_STACK instead of TCG_REG_R12
  TCG/IA64: use stack for TCG temps
  TCG/MIPS: use TCG_REG_CALL_STACK instead of TCG_REG_SP
  TCG/MIPS: use stack for TCG temps
  TCG/PPC: use TCG_REG_CALL_STACK instead of TCG_REG_R1
  TCG/PPC: use stack for TCG temps
  TCG/s390: use TCG_REG_CALL_STACK instead of TCG_REG_R15
  TCG/s390: use stack for TCG temps
  Remove temp_buf, rename CPU_TEMP_BUF_NLONGS
