* lit: Provide source locations in cfg files with older Python versionsAlp Toker2014-01-11
| | | | | | | | | This commit prospectively brings the benefits of r198766 to older supported Python versions (2.5+). Tested with Python 2.6, 2.7, 3.1 and 3.3 (!) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199009 91177308-0d34-0410-b5e6-96231b3b80d8
* lit: execfile() isn't present in Python 3.3Alp Toker2014-01-11
| | | | | | | | | | | | On the other hand, exec(compile()) doesn't work in older Python versions in the 2.x series. This commit introduces exec(compile()) with a fallback to plain exec(). That'll hopefully hit the sweet spot in terms of version support. Followup to r198766 which added enhanced source locations for lit cfg parsing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199006 91177308-0d34-0410-b5e6-96231b3b80d8

* Add support for positionally-encoded operands to FixedLenDecoderEmitterHal Finkel2013-12-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unfortunately, the PowerPC instruction definitions make heavy use of the positional operand encoding heuristic to map operands onto bitfield variables in the instruction definitions. Changing this to use name-based mapping is not trivial, however, because additional infrastructure needs to be designed to handle mapping of complex operands (with multiple suboperands) onto multiple bitfield variables. In the mean time, this adds support for positionally encoded operands to FixedLenDecoderEmitter, so that we can generate a disassembler for the PowerPC backend. To prevent an accidental reliance on this feature, and to prevent an undesirable interaction with existing disassemblers, a backend must opt-in to this support by setting the new decodePositionallyEncodedOperands instruction-set bit to true. When enabled, this iterates the variables that contribute to the instruction encoding, just as the encoder does, and emulates the procedure the encoder uses to map "numbered" operands to variables. The bit range for each variable is also determined as the encoder determines them. This map is then consulted during the decoder-generator's loop over operands to decode, allowing the decoder to understand both position-based and name-based operand-to-variable mappings. As noted in the comment on the decodePositionallyEncodedOperands definition, this support should be removed once it is no longer needed. There should be no change to existing disassemblers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197691 91177308-0d34-0410-b5e6-96231b3b80d8
* Add support for PointerLikeRegClass to FixedLenDecoderEmitterHal Finkel2013-12-19
| | | | | | | | This is more prep for adding the PowerPC disassembler. FixedLenDecoderEmitter should recognize PointerLikeRegClass operands as register types, and generate register-like decoding calls instead of treating them like immediates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197680 91177308-0d34-0410-b5e6-96231b3b80d8
* Support little-endian encodings in the FixedLenDecoderEmitterHal Finkel2013-12-17
| | | | | | | | | | | | | | | The convention used to specify the PowerPC ISA is that bits are numbered in reverse order (0 is the index of the high bit). To support this "little endian" encoding convention, CodeEmitterGen will reverse the bit numberings prior to generating the encoding tables. In order to generate a disassembler, FixedLenDecoderEmitter needs to do the same. This moves the bit reversal logic out of CodeEmitterGen and into CodeGenTarget (where it can be used by both CodeEmitterGen and FixedLenDecoderEmitter). This is prep work for disassembly support in the PPC backend (which is the only in-tree user of this little-endian encoding support). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197532 91177308-0d34-0410-b5e6-96231b3b80d8
