2009-04-01Add llvm::Triple class for abstracting access to target triples.Daniel Dunbar
- The code is silly, I'm just amusing myself. Rewrite to be efficient if you like. :) Also, if you wish to debate the proper names of the triple components I'm all ears. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68252 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-01Use CHAR_BIT instead of hard-coding 8 in several places where itDan Gohman
is appropriate. This helps visually differentiate host-oriented calculations from target-oriented calculations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68227 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-23Fix internal representation of fp80 to be theDale Johannesen
same as a normal i80 {low64, high16} rather than its own {high64, low16}. A depressing number of places know about this; I think I got them all. Bitcode readers and writers convert back to the old form to avoid breaking compatibility. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67562 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-17raw_ostream: Rework implementation of unbuffered streams so outputtingDaniel Dunbar
a single character requires only one branch to follow slow path. - Never use a buffer when writing on an unbuffered stream. - Move default buffer size to header. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67066 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-16raw_ostream: Replace flush_impl with write_impl, which takes data toDaniel Dunbar
write as arguments. - Add raw_ostream::GetNumBytesInBuffer. - Privatize buffer pointers. - Get rid of slow and unnecessary code for writing out large strings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67060 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-16raw_ostream: Lift out flush_nonempty.Daniel Dunbar
- Flush a known non-empty buffers; enforces the interface to flush_impl and kills off HandleFlush (which I saw no reason to be an inline method, Chris?). - Clarify invariant that flush_impl is only called with OutBufCur > OutBufStart. - This also cleary collects all places where we have to deal with the buffer possibly not existing. - A few more comments and fixing the unbuffered behavior remain in this commit sequence. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67057 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-13Fix a hashing bug in APInt. A certain pathological testcase (tooStuart Hastings
large for the testsuite) took over six minutes to compile on my Mac. The patched LLVM-GCC compiles that testcase in three seconds (GCC takes less than one second). This hash function is more complex (about 35 instructions on x86) than what Chris wanted, but I expect it will be well-behaved with arbitrary inputs. Thank you to everyone who responded to my previous request for advice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66962 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-17The debugger sometimes lookup dynamically in the runtime to find ivar info ↵Devang Patel

2009-01-23Introduce two DWARF attribute extentions DW_AT_APPLE_optimized, ↵Devang Patel
DW_AT_APPLE_flags. DW_AT_APPLE_optimized flag is set when a compile_unit is optimized. The debugger takes advantage of this information some way. DW_AT_APPLE_flags encodes command line options when certain env. variable is set. This is used by build engineers to track various gcc command lines used by by a project, irrespective of whether the project used makefile, Xcode or something else. llvm-gcc patch is next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62888 91177308-0d34-0410-b5e6-96231b3b80d8
