2011-03-17Stats: Update the statistics for rfe patch.Ali Saidi
2011-03-17ARM: Fix RFE macrop.Matt Horsnell
This changes the RFE macroop into 3 microops: URa = [sp]; URb = [sp+4]; // load CPSR,PC values from stack sp = sp + offset; // optionally auto-increment PC = URa; CPSR = URb; // write to the PC and CPSR. Importantly: - writing to PC is handled in the last micro-op. - loading occurs prior to state changes.
2011-03-17ARM: Rename registers used as temporary state by microops.Matt Horsnell
2011-03-17O3: Send instruction back to fetch on squash to seed predecoder correctly.Ali Saidi
2011-03-17O3: Cleanup the commitInfo comm struct.Ali Saidi
Get rid of unused members and use base types rather than derrived values where possible to limit amount of state.
2011-03-17ARM: Previous change didn't end up setting instFlags, this does.Ali Saidi
2011-03-17O3: Update regressions for mem block caching change.Ali Saidi
2011-03-17Mem: Fix issue with dirty block being lost when entire block transferred to ↵Ali Saidi
non-cache. This change fixes the problem for all the cases we actively use. If you want to try more creative I/O device attachments (E.g. sharing an L2), this won't work. You would need another level of caching between the I/O device and the cache (which you actually need anyway with our current code to make sure writes propagate). This is required so that you can mark the cache in between as top level and it won't try to send ownership of a block to the I/O device. Asserts have been added that should catch any issues.
2011-03-17O3: Fix unaligned stores when cache blockedAli Saidi
Without this change the a store can be issued to the cache multiple times. If this case occurs when the l1 cache is out of mshrs (and thus blocked) the processor will never make forward progress because each cycle it will send a single request using the recently freed mshr and not completing the multipart store. This will continue forever.

2011-03-12Regressions: Make X86_FS run automatically.Gabe Black
2011-03-11SCons: Stop embedding the mercurial revision into the binary.Gabe Black
This causes a lot of rebuilds that could have otherwise possibly been avoided, and, more annoyingly, a lot of unnecessary rerunning of the regressions. The benefits of having the revision in the output haven't materialized, so this change removes it.
2011-03-11Gems: Eliminate the now unused GEMS_ROOT scons variable.Gabe Black
2011-03-11Ruby: Get rid of the dead ruby tester.Gabe Black
None of the code in the ruby tester directory is compiled or referred to outside of that directory. This change eliminates it. If it's needed in the future, it can be revived from the history. In the mean time, this removes clutter and the only use of the GEMS_ROOT scons variable.

2011-03-03Mips: MIPS_FS doesn't build currently, so delete it to avoid confusion.Gabe Black
MIPS_FS doesn't build and presumably doesn't work right now. Users might see the MIP_FS file in build_opts and expect it to work. To avoid confusion, this change deletes that file.

the pc.
2011-03-02X86: Decode the mysterious and elusive ffreep x87 instruction.Gabe Black
The internet says this instruction was created by accident when an Intel CPU failed to decode x87 instructions properly. It's been documented on a few rare occasions and has generally worked to ensure backwards compatability. One source claims that the gcc toolchain is basically the only thing that emits it, and that emulators/binary translators like qemu and bochs implement it. We won't actually implement it here since we're hardly implementing any other x87 instructions either. If we were to implement it, it would behave the same as ffree but then also pop the register stack. http://www.pagetable.com/?p=16
2011-03-01Spelling: Fix the a spelling error by changing mmaped to mmapped.Gabe Black
There may not be a formally correct spelling for the past tense of mmap, but mmapped is the spelling Google doesn't try to autocorrect. This makes sense because it mirrors the past tense of map->mapped and not the past tense of cape->caped. --HG-- rename : src/arch/alpha/mmaped_ipr.hh => src/arch/alpha/mmapped_ipr.hh rename : src/arch/arm/mmaped_ipr.hh => src/arch/arm/mmapped_ipr.hh rename : src/arch/mips/mmaped_ipr.hh => src/arch/mips/mmapped_ipr.hh rename : src/arch/power/mmaped_ipr.hh => src/arch/power/mmapped_ipr.hh rename : src/arch/sparc/mmaped_ipr.hh => src/arch/sparc/mmapped_ipr.hh rename : src/arch/x86/mmaped_ipr.hh => src/arch/x86/mmapped_ipr.hh

2011-03-01X86: Mark prefetches as such in their instruction and request flags.Gabe Black
2011-03-01Ruby: Fix DPRINTF bugs in PerfectSwitch and MessageBufferNilay Vaish
At a couple of places in PerfectSwitch.cc and MessageBuffer.cc, DPRINTF() has not been provided with correct number of arguments. The patch fixes these bugs.
2011-03-01SCons: Separately label the global non-sticky options.Gabe Black
The global sticky options were being printed with a heading, and then the global nonsticky options were being printed immediately after them without a heading. Because the two lists ran together and the first had its own heading, it looked like -all- those options where sticky even though some of them aren't. This change adds a label to the second list so it's clear they're different.
2011-03-01Ruby: Mention that Ruby's bound checking option only applies to Ruby.Gabe Black

2011-02-26getopt: Remove GPL code.Nathan Binkert
This code is unused and should never have been committed
2011-02-25Ruby: Remove store bufferNilay Vaish
This patch removes the store buffer from Ruby. It is not in use currently. Since libruby is being and store buffer makes calls to libruby, it is not possible to maintain it until substantial changes are made.
2011-02-25Ruby: Remove librubyNilay Vaish
This patch removes libruby_internal.hh, libruby.hh and libruby.cc. It moves the contents to libruby.hh to RubyRequest.hh and RubyRequest.cc files.
2011-02-25Ruby: Make Address.hh independent of RubySystemNilay Vaish
This patch changes Address.hh so that it is not dependent on RubySystem. This dependence seems unecessary. All those functions that depend on RubySystem have been moved to Address.cc file.
2011-02-25Ruby: Make DataBlock.hh independent of RubySystemNilay Vaish
This patch changes DataBlock.hh so that it is not dependent on RubySystem. This dependence seems unecessary. All those functions that depende on RubySystem have been moved to DataBlock.cc file.
