* Introducing nocapture, a parameter attribute for pointers to indicate that theNick Lewycky2008-12-152-1/+24
| | | | | | | | | | | | | | | | | | | | | | | | | callee will not introduce any new aliases of that pointer. The attributes had all bits allocated already, so I decided to collapse alignment. Alignment was previously stored as a 16-bit integer from bits 16 to 32 of the attribute, but it was required to be a power of 2. Now it's stored in log2 encoded form in five bits from 16 to 21. That gives us 11 more bits of space. You may have already noticed that you only need four bits to encode a 16-bit power of two, so why five bits? Because the AsmParser accepted 32-bit alignments, even though we couldn't store them (they were silently discarded). Now we can store them in memory, but not in the bitcode. The bitcode format was already storing these as 64-bit VBR integers. So, the bitcode format stays the same, keeping the alignment values stored as 16 bit raw values. There's some hideous code in the reader and writer that deals with this, waiting to be ripped out the moment we run out of bits again and have to replace the parameter attributes table encoding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61019 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | bitcode reader/writer as follows: - add and use new bitcode FUNC_CODE_INST_VSELECT to handle the llvm select opcode using either i1 or [N x i1] as the selector. - retain old BITCODE FUNC_CODE_INST_SELECT in the bitcode reader to handle select on i1 for backwards compatibility with existing bitcode files. - re-enable the vector-select.ll test program. Also, rename the recently added bitcode opcode FUNC_CODE_INST_VCMP to FUNC_CODE_INST_CMP2 and make the bitcode writer use it to handle fcmp/icmp on scalars or vectors. In the bitcode writer, use FUNC_CODE_INST_CMP for vfcmp/vicmp only. In the bitcode reader, have FUNC_CODE_INST_CMP handle icmp/fcmp returning bool, for backwards compatibility with existing bitcode files.

* Rename some GC classes so that their roll will hopefully be clearer.Gordon Henriksen2008-08-172-18/+18
| | | | | | | | | | | | | | | | | | In particular, Collector was confusing to implementors. Several thought that this compile-time class was the place to implement their runtime GC heap. Of course, it doesn't even exist at runtime. Specifically, the renames are: Collector -> GCStrategy CollectorMetadata -> GCFunctionInfo CollectorModuleMetadata -> GCModuleInfo CollectorRegistry -> GCRegistry Function::getCollector -> getGC (setGC, hasGC, clearGC) Several accessors and nested types have also been renamed to be consistent. These changes should be obvious. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54899 91177308-0d34-0410-b5e6-96231b3b80d8
* Enable first-class aggregates support.Dan Gohman2008-07-232-18/+27

Also, remove support for return instructions with multiple values. These are auto-upgraded to use InsertValueInst instructions.

* Add a little wrapper header that is put around bc files when emittingChris Lattner2008-07-092-2/+125
| | | | | | | | | | | | | | | | | bc files for modules with a target triple that indicates they are for darwin. The reader unconditionally handles this, and the writer could turn this on for more targets if we care. This change has two benefits for darwin: 1) it allows us to encode the cpu type of the file in an easy to read place that doesn't require decoding the bc file. 2) it works around a bug (IMO) in darwin's AR where it is incapable of handling files that are not a multiple of 8 bytes long. BC files are only guaranteed to be multiples of 4 bytes long. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53275 91177308-0d34-0410-b5e6-96231b3b80d8
