* Remove all checking for the various terminfo headers (term.h andChandler Carruth2013-08-126-252/+11
| | | | | | | | | | | | | | | | curses.h). Finding these headers is next to impossible. For example, on Debian systems libtinfo-dev provides the terminfo reading library we want, but *not* term.h. For the header, you have to use libncurses-dev. And libncursesw-dev provides a *different* term.h in a different location! These headers aren't worth it. We want two functions the signatures of which are clearly spec'ed in sys-v and other documentation. Just declare them ourselves and call them. This should fix some debian builders and provide better support for "minimal" debian systems that do want color autodetection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188165 91177308-0d34-0410-b5e6-96231b3b80d8
* Stablize MCK_Reg ordering in AsmMatcherEmitterRichard Sandiford2013-08-121-19/+21
| | | | | | | | | | | | | | | | clang bootstraps intermittently failed for me due a difference in the MCK_Reg ordering in ARMGenAsmMatcher.inc. E.g. in my latest run the stage 1 and stage 3 versions were the same but the stage 2 one was different (though still functionally correct). This meant that the .o comparison failed. MCK_Regs were assigned by iterating over a std::set< std::set<Record*> >, and since std::set is sorted lexicographically, the order depended on the order of the pointer values. This patch replaces the pointer ordering with LessRecordByID. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188164 91177308-0d34-0410-b5e6-96231b3b80d8

* Target a minimal terminfo library rather than necessarily a full cursesChandler Carruth2013-08-129-80/+100
| | | | | | | | | | | | | | | | | | | | library for color support detection. This still will use a curses library if that is all we have available on the system. This change tries to use a smaller subset of the curses library, specifically the subset that is on some systems split off into a separate library. For example, if you install ncurses configured --with-tinfo, a 'libtinfo' is install that provides just the terminfo querying functionality. That library is now used instead of curses when it is available. This happens to fix a build error on systems with that library because when we tried to link ncurses into the binary, we didn't pull tinfo in as well. =] It should also provide an easy path for supporting the NetBSD libterminfo library, but as I don't have access to a NetBSD system I'm leaving adding that support to those folks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188160 91177308-0d34-0410-b5e6-96231b3b80d8

* Introduce factory methods for SpecialCaseListAlexey Samsonov2013-08-123-13/+92
| | | | | | | | | | | | | | | | | | | | Summary: Doing work in constructors is bad: this change suggests to call SpecialCaseList::create(Path, Error) instead of "new SpecialCaseList(Path)". Currently the latter may crash with report_fatal_error, which is undesirable - sometimes we want to report the error to user gracefully - for example, if he provides an incorrect file as an argument of Clang's -fsanitize-blacklist flag.

* Re-instate r187323 which fast-tracks promotable allocas as soon as theChandler Carruth2013-08-111-12/+81
| | | | | | | | | | | | | | | | | | | | | | | | | SROA-based analysis has enough information. This should work now that both mem2reg *and* the SSAUpdater-based AllocaPromoter have been updated to be able to promote the types of allocas that the SROA analysis detects. I've included tests for the AllocaPromoter that were only possible to write once we fast-tracked promotable allocas without rewriting them. This includes a test both for r187347 and r188145. Original commit log for r187323: """ Now that mem2reg understands how to cope with a slightly wider set of uses of an alloca, we can pre-compute promotability while analyzing an alloca for splitting in SROA. That lets us short-circuit the common case of a bunch of trivially promotable allocas. This cuts 20% to 30% off the run time of SROA for typical frontend-generated IR sequneces I'm seeing. It gets the new SROA to within 20% of ScalarRepl for such code. My current benchmark for these numbers is PR15412, but it fits the general pattern of IR emitted by Clang so it should be widely applicable.

| | | | | | | | | | | | | | | | | | | | the more general set of patterns that are now handled by mem2reg and that we can detect quickly while doing SROA's initial analysis. Notably, this allows it to promote through no-op bitcast and GEP sequences. A core part of the SSAUpdater approach is the ability to test whether a particular instruction is part of the set being promoted. Testing this becomes significantly more complex in the world where the operand to every load and store isn't the alloca itself. I ended up using the approach of walking up the def-chain until we find the alloca. I benchmarked this against keeping a set of pointer operands and keeping a set of the loads and stores we care about, and this one seemed faster although the difference was very small. No test case yet because currently the rewriting always "fixes" the inputs to not require this. The next patch which re-enables early promotion of easy cases in SROA will include a test case that specifically exercises this aspect of the alloca promoter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188145 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix assembling of Thumb2 branch instructions.Mihai Popa2013-08-0910-16/+451
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The long encoding for Thumb2 unconditional branches is broken. Additionally, there is no range checking for target operands; as such for instructions originating in assembly code, only short Thumb encodings are generated, regardless of the bitsize needed for the offset. Adding range checking is non trivial due to the representation of Thumb branch instructions. There is no true difference between conditional and unconditional branches in terms of operands and syntax - even unconditional branches have a predicate which is expected to match that of the IT block they are in. Yet, the encodings and the permitted size of the offset differ. Due to this, for any mnemonic there are really 4 encodings to choose for. The problem cannot be handled in the parser alone or by manipulating td files. Because the parser builds first a set of match candidates and then checks them one by one, whatever tablegen-only solution might be found will ultimately be dependent of the parser's evaluation order. What's worse is that due to the fact that all branches have the same syntax and the same kinds of operands, that order is governed by the lexicographical ordering of the names of operand classes... To circumvent all this, any necessary disambiguation is added to the instruction validation pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188067 91177308-0d34-0410-b5e6-96231b3b80d8
