* Add SPIR32/SPIR64 targets to ClangGuy Benyei2012-12-111-0/+98

* Speed up looking up static diagnostic infos.Benjamin Kramer2012-12-111-8/+41
| | | | | | | | | | | Instead of doing a binary search over the whole diagnostic table (which weighs a whopping 48k on x86_64), use the existing enums to compute the index in the table. This avoids loading any unneeded data from the table and avoids littering CPU caches with it. This code is in a hot path for code with many diagnostics. 1% speedup on -fsyntax-only gcc.c, which emits a lot of warnings. llvm-svn: 169890
* Extend stat query APIs to explicitly specify if the query is forArgyrios Kyrtzidis2012-12-112-21/+19
| | | | | | | | | | a file or directory, allowing just a stat call if a file descriptor is not needed. Doing just 'stat' is faster than 'open/fstat/close'. This has the effect of cutting down system time for validating the input files of a PCH. llvm-svn: 169831
* Virtual method overrides can no longer have mismatched calling conventions. ↵Aaron Ballman2012-12-091-4/+4
| | | | | | This fixes PR14339. llvm-svn: 169705
* long double should be 64 bits on FreeBSD/MIPS64. It possibly should be onDavid Chisnall2012-12-081-0/+4
| | | | | | | | Linux too, as I think we inherited it from there. The ABI spec says 128-bit, although I think SGI's compiler on IRIX may be the only thing ever to support this. llvm-svn: 169674
* Fix analysis based warnings so that all warnings are emitted when compilingDeLesley Hutchins2012-12-072-0/+5
| | | | | | | | | with -Werror. Previously, compiling with -Werror would emit only the first warning in a compilation unit, because clang assumes that once an error occurs, further analysis is unlikely to return valid results. However, warnings that have been upgraded to errors should not be treated as "errors" in this sense. llvm-svn: 169649
* Adapt to LLVM commit 169291 which streamlines the usage of NaCl/NativeClientEli Bendersky2012-12-041-4/+4

* Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth2012-12-0410-19/+17
| | | | | | | | | | | | | uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. llvm-svn: 169237
* Don't emit a warning with an input/output parameter. We assume the user ↵Bill Wendling2012-11-301-1/+3

* Don't warn if the input size is less than the register size. Also don't warn ifBill Wendling2012-11-301-1/+3
| | | | | | | the output size is greater than the register size. No truncation occurs with those. Reword warning to make it clearer what's the problem is. llvm-svn: 169054

* Add missing "break". Thanks to Craig for spotting it.Eli Friedman2012-11-261-0/+1
| | | | | | I'm looking at ways to fix the relevant test so it can catch this sort of mistake. llvm-svn: 168618
* Enable inlining of 4 byte atomic ops on ppc32, 8 byte atomic ops on ppc64.Benjamin Kramer2012-11-171-1/+6
| | | | | | Also fixes a bit/byte mismatch when checking if a target supports atomic ops of a certain size. llvm-svn: 168260

* Add -cc1 option -fno-diagnostics-use-presumed-location, a handy mode forRichard Smith2012-11-141-2/+3
| | | | | | | | | working with preprocessed testcases. This causes source locations in diagnostics to point at the spelling location instead of the presumed location, while still keeping the semantic effects of the line directives (entering and leaving system-header mode, primarily). llvm-svn: 168004
* Remove the cellspu port.Eric Christopher2012-11-141-9/+5
| | | | | | Approved by Chris Lattner. llvm-svn: 167983
* The register constraint could mean a 16- or 8-bit register.Bill Wendling2012-11-121-1/+1
| | | | llvm-svn: 167735
* Check that the input size is correct for the given constraint.Bill Wendling2012-11-121-0/+13
| | | | | | | | | The 'a', 'c', and 'd' constraints on i386 mean a 32-bit register. We cannot place a 64-bit value into the 32-bit register. Error out instead of causing the compiler to spew general badness. <rdar://problem/12415959> llvm-svn: 167717
* Remove unneeded includes from IdentifierTableNico Weber2012-11-111-1/+0
| | | | llvm-svn: 167694
* Add clang support of RTM from TSXMichael Liao2012-11-101-3/+19
| | | | | | | | | | | | - New options '-mrtm'/'-mno-rtm' are added to enable/disable RTM feature - Builtin macro '__RTM__' is defined if RTM feature is enabled - RTM intrinsic header is added and introduces 3 new intrinsics, namely '_xbegin', '_xend', and '_xabort'. - 3 new builtins are added to keep compatible with gcc, namely '__builtin_ia32_xbegin', '__builtin_ia32_xend', and '__builtin_ia32_xabort'. - Test cases for pre-defined macro and new intrinsic codegen are added. llvm-svn: 167665

* Set TLSSupported to false on Haiku.Benjamin Kramer2012-11-081-0/+1
| | | | | | | | | | | Haiku does not support this (yet). Leaving it set to true leads to configure scripts detecting __thread being available and Clang emitting code for it, resulting in binaries the runtime_loader will refuse to load. Patch by Jonathan Schleifer! llvm-svn: 167576
* Basic: Windows doesn't define S_IFIFO.Daniel Dunbar2012-11-061-1/+4
| | | | llvm-svn: 167468
* Frontend: Add support for reading named pipes as the main file.Daniel Dunbar2012-11-051-0/+4
| | | | | | | | - The whole {File,Source}Manager is built around wanting to pre-determine the size of files, so we can't fit this in naturally. Instead, we handle it like we do STDIN, where we just replace the main file contents upfront. llvm-svn: 167419

* This patch adds alignment information for long double to the 64-bit PowerPCBill Schmidt2012-10-291-3/+10
| | | | | | | | | | | | | | | | | | ELF subtarget. The existing description string is moved from PPC64TargetInfo to its DarwinTargetInfo subclass, to avoid any changes to the Darwin ABI. PPC64TargetInfo now has two possible description strings: one for FreeBSD, which requires 8-byte alignment, and a default string that requires 16-byte alignment. I've added a test for PPC64 Linux to verify the 16-byte alignment. If somebody wants to add a separate test for FreeBSD, that would be great. Note that there is a companion patch to update the alignment information in LLVM, which I am committing now as well. llvm-svn: 166927
* Handle '*' and '#' asm constraint modifiers.Ulrich Weigand2012-10-291-0/+4

* Recommit Eric's code to validate ASM string's constraints and modifiers.Bill Wendling2012-10-251-0/+24
| | | | | | | | | | | | | This code checks the ASM string to see if the output size is able to fit within the variable specified as the output. For instance, scalar-to-vector conversions may not really work. It's on by default, but can be turned off with a flag if you think you know what you're doing. This is placed under a flag ('-Wasm-operand-widths') and flag group ('-Wasm'). <rdar://problem/12284092> llvm-svn: 166737

* Serialize TargetOptions into an AST file, and make sure that we keepDouglas Gregor2012-10-161-4/+8
| | | | | | | target options around so they can be accessed at any point (rather than keeping them transient). llvm-svn: 166072
* Add pnaclcall convention to Native Client targets.Derek Schuff2012-10-161-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | Because PNaCl bitcode must be target-independent, it uses some different bitcode representations from other targets (e.g. byval and sret for structures). This means that without additional type information, it cannot meet some native ABI requirements for some targets (e.g. passing structures containing unions by value on x86-64). To allow generation of code which uses the correct native ABIs, we also support triples such as x86_64-nacl, which uses target-dependent IR (as opposed to le32-nacl, which uses byval and sret). To allow interoperation between the two types of code, this patch adds a calling convention attribute to be used in code compiled with the target-dependent triple, which will generate code using the le32-style bitcode. This calling convention does not need to be explicitly supported in the backend because it determines bitcode representation rather than native conventions (the backend just needs to undersand how to handle byval and sret for the Native Client OS). This patch implements __attribute__((pnaclcall)) to generate calls in bitcode according to the le32 bitcode conventions, an attribute which is accepted by any Native Client target, but issues a warning otherwise. llvm-svn: 166065
