Since there was a version 2 of one of the previous patches, I'll call this set version 3. These patches completely replace the previous patches.
As before, these are for a future PowerPC machine that we are looking at. If a real machine is announced that uses these instructions, we may change the name used in the -mcpu=<machine> option to be the real machine, and drop the 'future' name. I tried to make the changes suggested in the previous patch set, and keep things that use the address masks (i.e. RELOAD_REG_*) confined to rs6000.c. To recap: Patch #1: Basic changes to enable pcrel addresses using PLA/PLD; Patch #2: Optional rework rs6000_setup_reg_addr_mask; Patch #3: Add prefixed RTL support; Patch #4: Add prefixed load/store to all offset instructions; Patch #5: Optionally enable pc-relative on Linux 64-bit ELFv2; Patch #6: Fix a limitation with vector extracts & pcrel addresses; Patch #7: Add PCREL_OPT support; Patch #8: Misc. tests; Patch #9: Prefixed load/store tests with large numeric offsets; Patch #10: Pc-relative load/store tests. I have built each of patches 1-7 in succession, building a bootstrapped compiler and running make check. There were no regressions. I then reran the tests with patches 8-10 applied, and all of the new patches also pass. -- Michael Meissner, IBM IBM, M/S 2506R, 550 King Street, Littleton, MA 01460-6245, USA email: meiss...@linux.ibm.com, phone: +1 (978) 899-4797
