* Remove edis - the enhanced disassembler. Fixes PR14654.Roman Divacky2012-12-19

* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-03
| | | | | | | | | | | | | | | | | Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8

* Switch the fixed-length disassembler to be table-driven.Jim Grosbach2012-08-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor the TableGen'erated fixed length disassemblmer to use a table-driven state machine rather than a massive set of nested switch() statements. As a result, the ARM Disassembler (ARMDisassembler.cpp) builds much more quickly and generates a smaller end result. For a Release+Asserts build on a 16GB 3.4GHz i7 iMac w/ SSD: Time to compile at -O2 (averaged w/ hot caches): Previous: 35.5s New: 8.9s TEXT size: Previous: 447,251 New: 297,661 Builds in 25% of the time previously required and generates code 66% of the size. Execution time of the disassembler is only slightly slower (7% disassembling 10 million ARM instructions, 19.6s vs 21.0s). The new implementation has not yet been tuned, however, so the performance should almost certainly be recoverable should it become a concern. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161888 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | rdar://10873652 As part of this I updated the llvm-mc disassembler C API to always call the SymbolLookUp call back even if there is no getOpInfo call back. If there is a getOpInfo call back that is tried first and then if that gets no information then the SymbolLookUp is called. I also made the code more robust by memset(3)'ing to zero the LLVMOpInfo1 struct before then setting SymbolicOp.Value before for the call to getOpInfo. And also don't use any values from the LLVMOpInfo1 struct if getOpInfo returns 0. And also don't use any of the ReferenceType or ReferenceName values from SymbolLookUp if it returns NULL. rdar://10873563 and rdar://10873683 For the X86 target also fixed bugs so the annotations get printed. Also fixed a few places in the ARM target that was not producing symbolic operands for some instructions. rdar://10878166 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151267 91177308-0d34-0410-b5e6-96231b3b80d8
