2013-04-05Reapply r178845 with fix - Fix bug in PEI's virtual-register scavengingHal Finkel
This fixes PEI as previously described, but correctly handles the case where the instruction defining the virtual register to be scavenged is the first in the block. Arnold provided me with a bugpoint-reduced test case, but even that seems too large to use as a regression test. If I'm successful in cleaning it up then I'll commit that as well. Original commit message: This change fixes a bug that I introduced in r178058. After a register is scavenged using one of the available spills slots the instruction defining the virtual register needs to be moved to after the spill code. The scavenger has already processed the defining instruction so that registers killed by that instruction are available for definition in that same instruction. Unfortunately, after this, the scavenger needs to iterate through the spill code and then visit, again, the instruction that defines the now-scavenged register. In order to avoid confusion, the register scavenger needs the ability to 'back up' through the spill code so that it can again process the instructions in the appropriate order. Prior to this fix, once the scavenger reached the just-moved instruction, it would assert if it killed any registers because, having already processed the instruction, it believed they were undefined. Unfortunately, I don't yet have a small test case. Thanks to Pranav Bhandarkar for diagnosing the problem and testing this fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178919 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-04CostModel: Add parameter to instruction cost to further classify operand valuesArnold Schwaighofer
On certain architectures we can support efficient vectorized version of instructions if the operand value is uniform (splat) or a constant scalar. An example of this is a vector shift on x86. We can efficiently support for (i = 0 ; i < ; i += 4) w[0:3] = v[0:3] << <2, 2, 2, 2> but not for (i = 0; i < ; i += 4) w[0:3] = v[0:3] << x[0:3] This patch adds a parameter to getArithmeticInstrCost to further qualify operand values as uniform or uniform constant. Targets can then choose to return a different cost for instructions with such operand values. A follow-up commit will test this feature on x86. radar://13576547 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178807 91177308-0d34-0410-b5e6-96231b3b80d8

Normally r_info is just a 32 of 64 bit number matching the endian of the rest of the file. Unfortunately, mips 64 bit little endian is special: The top 32 bits are a little endian number and the following 32 are a big endian one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178694 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-03Implements low-level object file format specific output for COFF andEric Christopher
ELF with support for: - File headers - Section headers + data - Relocations - Symbols - Unwind data (only COFF/Win64) The output format follows a few rules: - Values are almost always output one per line (as elf-dump/coff-dump already do). - Many values are translated to something readable (like enum names), with the raw value in parentheses. - Hex numbers are output in uppercase, prefixed with "0x". - Flags are sorted alphabetically. - Lists and groups are always delimited. Example output: ---------- snip ---------- Sections [ Section { Index: 1 Name: .text (5) Type: SHT_PROGBITS (0x1) Flags [ (0x6) SHF_ALLOC (0x2) SHF_EXECINSTR (0x4) ] Address: 0x0 Offset: 0x40 Size: 33 Link: 0 Info: 0 AddressAlignment: 16 EntrySize: 0 Relocations [ 0x6 R_386_32 .rodata.str1.1 0x0 0xB R_386_PC32 puts 0x0 0x12 R_386_32 .rodata.str1.1 0x0 0x17 R_386_PC32 puts 0x0 ] SectionData ( 0000: 83EC04C7 04240000 0000E8FC FFFFFFC7 |.....$..........| 0010: 04240600 0000E8FC FFFFFF31 C083C404 |.$.........1....| 0020: C3 |.| ) } ] ---------- snip ---------- Relocations and symbols can be output standalone or together with the section header as displayed in the example. This feature set supports all tests in test/MC/COFF and test/MC/ELF (and I suspect all additional tests using elf-dump), making elf-dump and coff-dump deprecated.

2013-04-02Count processor resources individually in MachineTraceMetrics.Jakob Stoklund Olesen
The new instruction scheduling models provide information about the number of cycles consumed on each processor resource. This makes it possible to estimate ILP more accurately than simply counting instructions / issue width. The functions getResourceDepth() and getResourceLength() now identify the limiting processor resource, and return a cycle count based on that. This gives more precise resource information, particularly in traces that use one resource a lot more than others. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178553 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-01Mips direct object exception handling regressionJack Carter
Revision 177141 caused a regression in all but mips64 little endian. That is because none of the other Mips targets had test cases checking the contents of the .eh_frame section. This patch fixes both the llvm code and adds an assembler test case to include the current 4 flavors. The test cases unfortunately rely on llvm-objdump. A preferable method would be to use a pretty printer output such as what readelf -wf <elf_file> would give. I also changed the name of the test case to correct a typo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178506 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-28Seciton 24.2.2 of the C++ standard, [iterator.iterators], Table 106Howard Hinnant
requires that the return type of *r for all iterators r be reference, where reference is defined in [iterator.requirements.general]/p11 as iterator_traits<X>::reference, and X is the type of r. But in CFG.h, the dereference operator of PredIterator and SuccIterator return pointer, not reference. Furthermore the nested type reference is value_type&, which is not the type returned from operator*(). This patch simply makes the iterator::reference type value_type*, which is what the operator*() returns, and then re-lables the return type as reference. From a functionality point of view, the only difference is that the nested reference type is now value_type* instead of value_type&. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178240 91177308-0d34-0410-b5e6-96231b3b80d8

As far as simplify_type is concerned, there are 3 kinds of smart pointers: * const correct: A 'const MyPtr<int> &' produces a 'const int*'. A 'MyPtr<int> &' produces a 'int *'. * always const: Even a 'MyPtr<int> &' produces a 'const int*'. * no const: Even a 'const MyPtr<int> &' produces a 'int*'. This patch then does the following: * Removes the unused specializations. Since they are unused, it is hard to know which kind should be implemented. * Make sure we don't drop const. * Fix the default forwarding so that const correct pointer only need one specialization. * Simplifies the existing specializations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178147 91177308-0d34-0410-b5e6-96231b3b80d8
