2010-05-14MC: Switch to completely lazy layout.Daniel Dunbar
- The eliminates the last major algorithmic problem with MC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103754 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-14MC: Extend MCAsmLayout to explicitly track which fragments have been layed ↵Daniel Dunbar
out, and enforce several invariants to LayoutFragment to ensure we only do layout in a sensible order. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103753 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103752 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-14MC: Switch MCFragment to storing the layout order index, not its index in ↵Daniel Dunbar
the file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103751 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-14MC: Change LayoutSection() to only do the section initializiation.Daniel Dunbar
Also, elimminate MCAsmLayout::set*, which are no longer needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103750 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-13MC: Move ordinal calculation, to make sure fragments synthesized for layout ↵Daniel Dunbar
get assigned ordinals properly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103711 91177308-0d34-0410-b5e6-96231b3b80d8

simplifies layout. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103710 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-13MC: Switch to using explicit MCAlignFragments with OnlyAlignAddress bit insteadDaniel Dunbar
of manually doing padding/editing layout in LayoutSection(). - This probably seems like six-of-one and half-dozen of another, but there is a method to my madness. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103693 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-13MC: Add MCAlignFragment::OnlyAlignAddress bit. This is a bit of magic that ↵Daniel Dunbar
says the align fragment shouldn't contribute to the logical section size, it is will be used for cleaning up the code to handle section alignment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103690 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-13MC: Add MCSectionData::AddressSize, which is the size of the address space ↵Daniel Dunbar
consumed by the section. This can differ from both the section logical size, and the section size on disk (although the current code handles this without making an explicit distinction). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103689 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103664 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-12MC: Explicitly check that only virtual fragments appear in virtual sections.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103663 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-12MC: Switch MCFillFragment to storing total fill size instead of a count. ↵Daniel Dunbar
This allows using ValueSize==0 to represent a virtual fill. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103662 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-12MC: Drop support for alignment in ZeroFill fragment, we can just useDaniel Dunbar
MCAlignFragments for this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103661 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103627 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103616 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-12MC/Mach-O/x86_64: Add a new hook for checking whether a particular section canDaniel Dunbar
be diced into atoms, and adjust getAtom() to take this into account. - This fixes relocations to symbols in fixed size literal sections, for example. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103532 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-11MC/Mach-O x86_64: Switch to using fragment atom symbol.Daniel Dunbar
- This eliminates getAtomForAddress() (which was a linear search) and simplifies getAtom(). - This also fixes some correctness problems where local labels at the same address as non-local labels could be assigned to the wrong atom. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103480 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-04llvm-mc: Fix case were we would skip a line in the .s file after an instructionDaniel Dunbar
match failure. Also, fixes a few memory leak FIXMEs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102986 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-25llvm-mc: Add a -mc-relax-all option, which relaxes every fixup. We always needDaniel Dunbar
exactly two passes in that case, and don't ever need to recompute any layout, so this is a nice baseline for relaxation performance. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99563 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-25MC: Stop restarting layout on every relaxation.Daniel Dunbar
- Still O(N^2), just a faster form, and now its the MCAsmLayout's fault. On the .s I am tuning against (combine.s from 403.gcc): -- ddunbar@lordcrumb:MC$ diff stats-before.txt stats-after.txt 5,10c5,10 < 1728 assembler - Number of assembler layout and relaxation steps < 7707 assembler - Number of emitted assembler fragments < 120588 assembler - Number of emitted object file bytes < 2233448 assembler - Number of evaluated fixups < 1727 assembler - Number of relaxed instructions < 6723845 mcexpr - Number of MCExpr evaluations --- > 3 assembler - Number of assembler layout and relaxation steps > 7707 assembler - Number of emitted assembler fragments > 120588 assembler - Number of emitted object file bytes > 14796 assembler - Number of evaluated fixups > 1727 assembler - Number of relaxed instructions > 67889 mcexpr - Number of MCExpr evaluations -- Feel free to LOL at the -before numbers, if you like. I am a little surprised we make more than 2 relaxation passes. It's pretty trivial for us to do relaxation out-of-order if that would give a speedup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99543 91177308-0d34-0410-b5e6-96231b3b80d8
