2009-08-04Avoid compiler warning (in -Asserts mode)Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78070 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-31switch off of 'Section' onto MCSection. We're not properly usingChris Lattner
MCSection subclasses yet, but this is a step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77708 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-31define target names for std libcalls.Sanjiv Gupta
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77667 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-29Move types back to the 2.5 API.Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77516 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-28Rip all of the global variable lowering logic out of TargetAsmInfo. SinceChris Lattner
it is highly specific to the object file that will be generated in the end, this introduces a new TargetLoweringObjectFile interface that is implemented for each of ELF/MachO/COFF/Alpha/PIC16 and XCore. Though still is still a brutal and ugly refactoring, this is a major step towards goodness. This patch also: 1. fixes a bunch of dangling pointer problems in the PIC16 backend. 2. disables the TargetLowering copy ctor which PIC16 was accidentally using. 3. gets us closer to xcore having its own crazy target section flags and pic16 not having to shadow sections with its own objects. 4. fixes wierdness where ELF targets would set CStringSection but not CStringSection_. Factor the code better. 5. fixes some bugs in string lowering on ELF targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77294 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-27Generate a libcall for i8 multiply.Sanjiv Gupta
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77179 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-27fixed incorrect lowering of ISD::SUB node. SUB has only one result value.Sanjiv Gupta
It wasn't caught during tests because we never got a sub generated, (i8 was always getting promoted to int, which in turn was broken into subc/sube). Though the optimizer leaves an i8 sub now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77178 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-21Remove shift amount flavor. It isn't actually complete enough to Eli Friedman
be useful, and it's currently unused. (Some issues: it isn't actually rich enough to capture the semantics on many architectures, and semantics can vary depending on the type being shifted.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76633 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-17Remove some unnecessary expansion markings. Add a few expansion Eli Friedman
markings that show up in test/CodeGen/Generic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76160 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-14llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin
This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75640 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-11assert(0) -> LLVM_UNREACHABLE.Torok Edwin
Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75379 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-09Thread LLVMContext through MVT and related parts of SDISel.Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75153 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-08Convert more abort() calls to llvm_report_error().Torok Edwin
Also remove trailing semicolon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75027 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-03For extended loads of type i1 to i8, we will need to at least one byte from ↵Sanjiv Gupta
memory. The change in the .td file is to mark the side effects of mov insn. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74768 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-03Add NumFixedArgs attribute to CallSDNode which indicates the number of fixed ↵Tilmann Scheller
arguments in a vararg call. With the SVR4 ABI on PowerPC, vector arguments for vararg calls are passed differently depending on whether they are a fixed or a variable argument. Variable vector arguments always go into memory, fixed vector arguments are put into vector registers. If there are no free vector registers available, fixed vector arguments are put on the stack. The NumFixedArgs attribute allows to decide for an argument in a vararg call whether it belongs to the fixed or variable portion of the parameter list. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74764 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-25Added floating point conditional operations support via libcalls.Sanjiv Gupta
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74187 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-23Fold the add (ptr, offset) into ptr[offset] only if the offset is small ↵Sanjiv Gupta
enough. movwi and moviw allow value of 5-bits only (i.e. 32). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73953 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-16Added missing libcalls for floating point to int conversions.Sanjiv Gupta
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73491 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-03Make the buildbot see green (to make it easier to spot the next personMike Stump
that puts a new warning in). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72797 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-03FrameIndex could be used as a value (addressof (arg)) or as an address.Sanjiv Gupta
Expand it exactly like GlobalAddress. Fix some more crashes (InsertBranch() not being implemented) for compiling hitec libs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72776 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-22Make the function begin label start after ther data pointer.Sanjiv Gupta
The address of data frame for function can be obtained by subtracting 2 from the function begin label. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69801 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-13While passing arg of types larger than char only one byte at lower end was ↵Sanjiv Gupta
getting passed. We couldn't catch this as we did not have tests that were passing an int value larger than 256. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68946 91177308-0d34-0410-b5e6-96231b3b80d8

fixed to start after return value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68705 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-09r68576 unconverd a bug in PIC16 port (Thanks to Dan Gohman) where we were ↵Sanjiv Gupta
custom lowering an ADD to ADDC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68671 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-08Emit .line debug directives for stoppoints. The debug location is retrieved ↵Sanjiv Gupta
by the MachineInstr itself, rather than by custom handling the DBG_STOPPOINT nodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68602 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-08Handle indirect function calls.Sanjiv Gupta
Every function has the address of its frame in the beginning of code section. The frame address is retrieved and used to pass arguments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68597 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-06Map stack based frameindices for spills to zero based indices that can be ↵Sanjiv Gupta
accessed based on an external symbol defining the location of temporary data for a function. For example: we have spill slots addressed as foo.tmp + 0, foo.tmp + 1 etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68442 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-02To convert the StopPoint insn into an assembler directive by ISel, we need ↵Sanjiv Gupta
to have access to the line number field. So we convert that info as an operand by custom handling DBG_STOPPOINT in legalize. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68329 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-02Params are not being generated as static globals now. The caller passes them ↵Sanjiv Gupta
onto the callee's stack directly and the callee loads the argvals from its own stack. Clang generated frameindexes validatd by recalculating the stack as if all frameindexes represent 1-byte slots. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68327 91177308-0d34-0410-b5e6-96231b3b80d8
