Subject: PowerPC future machine, version 3
Date: Mon, 26 Aug 2019 19:21:00 -0000 [thread overview]
Message-ID: <20190826173320.GA7958@ibm-toto.the-meissners.org> (raw)
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.
