* Make one of the AttributeSet ctors maintain the invariant that thePeter Collingbourne2013-08-02
| | | | | | | | attribute list is ordered by index. Differential Revision: http://llvm-reviews.chandlerc.com/D1265 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187682 91177308-0d34-0410-b5e6-96231b3b80d8
* Option parsing: recognize the special -- tokenHans Wennborg2013-08-02
| | | | | | | | | | | | | | Everything that comes after -- should be treated as a filename. This enables passing in filenames that would otherwise be conflated with command-line options. This is especially important for clang-cl which supports options starting with /, which are easily conflatable with Unix-style path names.

* Option parsing: remove non-SUPPORT_ALIASARGS fall-backHans Wennborg2013-07-31
| | | | | | | | The clients of this code have been updated to all support AliasArgs. This depends on Clang r187538 and lld r187541. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187546 91177308-0d34-0410-b5e6-96231b3b80d8
* Option parsing: add support for alias arguments.Hans Wennborg2013-07-31
| | | | | | | | | | | | | | | | | | This makes option aliases more powerful by enabling them to pass along arguments to the option they're aliasing. For example, if we have a joined option "-foo=", we can now specify a flag option "-bar" to be an alias of that, with the argument "baz". This is especially useful for the cl.exe compatible clang driver, where many options are aliases. For example, this patch enables us to alias "/Ox" to "-O3" (-O is a joined option), and "/WX" to "-Werror" (again, -W is a joined option).

* [APFloat] Make all arithmetic operations with NaN produce positive NaNs.Michael Gottesman2013-07-27
| | | | | | | | | | | | | IEEE-754R 1.4 Exclusions states that IEEE-754R does not specify the interpretation of the sign of NaNs. In order to remove an irrelevant variable that most floating point implementations do not use, standardize add, sub, mul, div, mod so that operating anything with NaN always yields a positive NaN. In a later commit I am going to update the APIs for creating NaNs so that one can not even create a negative NaN. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187314 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert "[PowerPC] Improve consistency in use of __ppc__, __powerpc__, etc."Rafael Espindola2013-07-26
| | | | | | This reverts commit r187248. It broke many bots. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187254 91177308-0d34-0410-b5e6-96231b3b80d8
* [PowerPC] Improve consistency in use of __ppc__, __powerpc__, etc.Bill Schmidt2013-07-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | Both GCC and LLVM will implicitly define __ppc__ and __powerpc__ for all PowerPC targets, whether 32- or 64-bit. They will both implicitly define __ppc64__ and __powerpc64__ for 64-bit PowerPC targets, and not for 32-bit targets. We cannot be sure that all other possible compilers used to compile Clang/LLVM define both __ppc__ and __powerpc__, for example, so it is best to check for both when relying on either inside the Clang/LLVM code base. This patch makes sure we always check for both variants. In addition, it fixes one unnecessary check in lib/Target/PowerPC/PPCJITInfo.cpp. (At least one of __ppc__ and __powerpc__ should always be defined when compiling for a PowerPC target, no matter which compiler is used, so testing for them is unnecessary.) There are some places in the compiler that check for other variants, like __POWERPC__ and _POWER, and I have left those in place. There is no need to add them elsewhere. This seems to be in Apple-specific code, and I won't take a chance on breaking it. There is no intended change in behavior; thus, no test cases are added. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187248 91177308-0d34-0410-b5e6-96231b3b80d8

* [mips] Use pristine object file while processing relocations.Akira Hatanaka2013-07-24
| | | | | | | | | | | | | | | | | | | | | Similar to ARM change r182800, dynamic linker will read bits/addends from the original object rather than from the object that might have been patched previously. For the purpose of relocations for MCJIT stubs on MIPS, we internally use otherwise unused MIPS relocations. The change also enables MCJIT unit tests for MIPS (EL/BE), and the following two tests now pass: - MCJITTest.return_global and - MCJITTest.multiple_functions. These issues have been tracked as Bug 16250. Patch by Petar Jovanovic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187019 91177308-0d34-0410-b5e6-96231b3b80d8
* Refactor the unit test for MemoryBuffer::getOpenFileSliceEli Bendersky2013-07-23
| | | | | | | | Run in two different modes: with and without reopening the temporary file between creating it and mapping it with MemoryBuffer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186986 91177308-0d34-0410-b5e6-96231b3b80d8
* Split getOpenFile into getOpenFile and getOpenFileSlice.Rafael Espindola2013-07-23
| | | | | | | | | | | | | | | | The main observation is that we never need both the filesize and the map size. When mapping a slice of a file, it doesn't make sense to request a null terminator and that would be the only case where the filesize would be used. There are other cleanups that should be done in this area: * A client should not have to pass the size (even an explicit -1) to say if it wants a null terminator or not, so we should probably swap the argument order. * The default should be to not require a null terminator. Very few clients require this, but many end up asking for it just because it is the default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186984 91177308-0d34-0410-b5e6-96231b3b80d8

* Option parsing: allow aliases in groupsHans Wennborg2013-07-22
| | | | | | | | | Option aliases in option groups were previously disallowed by an assert. As far as I can tell, there was no technical reason for this, and I would like to be able to put cl.exe compatible options in their own group for Clang, so let's change the assert. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186838 91177308-0d34-0410-b5e6-96231b3b80d8

Major behavior changes: - We can now parse UTF-16 files that have a byte order mark. - PR16209: Don't drop backslashes on the floor if they don't escape anything.

* Fix a regression I introduced back in r178147.Rafael Espindola2013-07-18
| | | | | | | | | | | We don't want cast and dyn_cast to work on temporaries. They don't extend lifetime like a direct bind to a reference would, so they can introduce hard to find bugs.

* Implement categories for special case lists.Peter Collingbourne2013-07-09
| | | | | | | | | | | | | | | | | | | | | | | | A special case list can now specify categories for specific globals, which can be used to instruct an instrumentation pass to treat certain functions or global variables in a specific way, such as by omitting certain aspects of instrumentation while keeping others, or informing the instrumentation pass that a specific uninstrumentable function has certain semantics, thus allowing the pass to instrument callers according to those semantics. For example, AddressSanitizer now uses the "init" category instead of global-init prefixes for globals whose initializers should not be instrumented, but which in all other respects should be instrumented. The motivating use case is DataFlowSanitizer, which will have a number of different categories for uninstrumentable functions, such as "functional" which specifies that a function has pure functional semantics, or "discard" which indicates that a function's return value should not be labelled.
