2012-12-11Speed up looking up static diagnostic infos.Benjamin Kramer
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169890 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-08long double should be 64 bits on FreeBSD/MIPS64. It possibly should be onDavid Chisnall
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169674 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-07Fix analysis based warnings so that all warnings are emitted when compilingDeLesley Hutchins
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169649 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-29This patch adds alignment information for long double to the 64-bit PowerPCBill Schmidt
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166927 91177308-0d34-0410-b5e6-96231b3b80d8

It's on by default, but can be turned off with a flag if you think you know what you're doing.

2012-10-16Add pnaclcall convention to Native Client targets.Derek Schuff
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166065 91177308-0d34-0410-b5e6-96231b3b80d8
