* [AVR] Add the ELF object file writerDylan McKay2016-09-302-0/+128
| | | | | | | | | | | | Summary: This adds the ELF32 writer for AVR. Reviewers: kparzysz Subscribers: beanz, mgorny Differential Revision: https://reviews.llvm.org/D25031 llvm-svn: 282856

* [AVR] Add the assembly instruction printerDylan McKay2016-09-306-2/+260
| | | | | | | | | | | | | | | | | Summary: This change adds the AVR assembly instruction printer. No tests are included in this patch. I have left them downstream so we can add them once `llc` successfully runs (there's very few components left to upstream until this).

* [RegAllocGreedy] Attempt to split unspillable live intervalsDylan McKay2016-09-301-6/+8
| | | | | | | | | | | | | | | | | | | | | | | Summary: Previously, when allocating unspillable live ranges, we would never attempt to split. We would always bail out and try last ditch graph recoloring. This patch changes this by attempting to split all live intervals before performing recoloring. This fixes LLVM bug PR14879. I can't add test cases for any backends other than AVR because none of them have small enough register classes to trigger the bug.

I'm not completely sure what this method does or why all the 256-bit VTs returned VR128RegClass when the comments on the method definiton say it should return the largest super register class. I just figured AVX-512 should be similar. llvm-svn: 282836

| | | | | | | | | | addRegisterClass regardless of whether AVX512/VLX is enabled or not. If AVX512 is disabled, the registers should already be marked reserved. Pattern predicates and register classes on instructions should take care of most of the rest. Loads/stores and physical register copies for XMM16-31 and YMM16-31 without VLX have already been taken care of. I'm a little unclear why this changed the register allocation of the SSE2 run of the sad.ll test, but the registers selected appear to be valid after this change. llvm-svn: 282835

| | | | | | | | | | For some reason there are both of these available, except for scalar 64-bit compares which only has u64. I'm not sure why there are both (I'm guessing it's for the one bit inputs we don't use), but for consistency always using the unsigned one. llvm-svn: 282832

| | | | | | | | | | | | | | (Recommit after making sure IsVerbose gets properly initialized in DiagnosticInfoOptimizationBase. See previous commit that takes care of this.) OptimizationRemarkAnalysis directly takes the role of the report that is generated by LAA. Then we need the magic to be able to turn an LAA remark into an LV remark.

* [RegisterBankInfo] Change the default mapping for Copy and PHI.Quentin Colombet2016-09-292-54/+37
| | | | | | | | | | | | | | Instead of producing a mapping for all the operands, we only generate a mapping for the definition. Indeed, the other operands are not constrained by the instruction and thus, we should leave the choice to the actual definition to do the right thing. In pratice this is almost NFC, but with one advantage. We will have only one instance of OperandsMapping for each copy and phi that map to one register bank instead of one different instance for each different number of operands for each copy and phi. llvm-svn: 282756

* [codeview] Use character types for all byte-sized integer typesReid Kleckner2016-09-291-10/+10
| | | | | | | | | | | | | | | The VS debugger doesn't appear to understand the 0x68 or 0x69 type indices, which were probably intended for use on a platform where a C 'int' is 8 bits. So, use the character types instead. Clang was already using the character types because '[u]int8_t' is usually defined in terms of 'char'.

| | | | | | | | | | The shuffle mask decodes have a large amount of repeated code extracting/splitting mask values from Constant data. This patch pulls all of this duplicated code into a single helper function to identify undef elements and combine/split constant integer data into the requested shuffle mask elements. Updated PSHUFB/VPERMIL/VPERMIL2/VPPERM decoders to use it (VPERMV/VPERMV3 could be converted as well in the future). llvm-svn: 282720
