* Options: explicit handling of --Hans Wennborg2013-08-13
| | | | | | | | | | | Clients of the option parsing library should handle it explicitly using a KIND_REMAINING_ARGS option. Clang and lld have been updated in r188316 and r188318, respectively. Also fix -Wsign-compare warning in the option parsing test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188323 91177308-0d34-0410-b5e6-96231b3b80d8
* Options: Add new option kind that consumes remaining argumentsHans Wennborg2013-08-13
| | | | | | | | | | | | | | | | This adds KIND_REMAINING_ARGS, a class of options that consume all remaining arguments on the command line. This will be used to support /link in clang-cl, which is used to forward all remaining arguments to the linker. It also allows us to remove the hard-coded handling of "--", allowing clients (clang and lld) to implement that functionality themselves with this new option class.

* Introduce factory methods for SpecialCaseListAlexey Samsonov2013-08-12
| | | | | | | | | | | | | | | | | | | | 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.

After reading the Unicode Standard I came up with the code that uses definitions of "printable" and "column width" more suitable for terminal output (i.e. fixed-width fonts and special treatment of many control characters). The implementation here can probably be used for Windows and MacOS if someone can test it properly. The patch addresses PR14910.

* 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

| | | | | | 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

* 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
