2013-04-21Passing arguments to varags functions under the SPARC v9 ABI.Jakob Stoklund Olesen
Arguments after the fixed arguments never use the floating point registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179987 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-21Fix the SETHIimm pattern for 64-bit code.Jakob Stoklund Olesen
Don't ignore the high 32 bits of the immediate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179985 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-20Compile varargs functions for SPARCv9.Jakob Stoklund Olesen
With a little help from the frontend, it looks like the standard va_* intrinsics can do the job. Also clean up an old bitcast hack in LowerVAARG that dealt with unaligned double loads. Load SDNodes can specify an alignment now. Still missing: Calling varargs functions with float arguments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179961 91177308-0d34-0410-b5e6-96231b3b80d8

Test case by llvm-stress. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179477 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-14Add support for the abs64 SPARC v9 code model.Jakob Stoklund Olesen
For when 16 TB just isn't enough. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179474 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-14Add support for the SPARC v9 abs44 code model.Jakob Stoklund Olesen
This is the default model for non-PIC 64-bit code. It supports text+data+bss linked anywhere in the low 16 TB of the address space. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179473 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-14Also put target flags on SPARC constant pool references.Jakob Stoklund Olesen
Constant pool entries are accessed exactly the same way as global variables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179471 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-14Fix patterns for 64-bit pointers.Jakob Stoklund Olesen
This fixes the pic32 code model for SPARC v9. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179469 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-13Define SPARC code models.Jakob Stoklund Olesen
Currently, only abs32 and pic32 are implemented. Add a test case for abs32 with 64-bit code. 64-bit PIC code is currently broken. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179463 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-09Compute correct frame sizes for SPARC v9 64-bit frames.Jakob Stoklund Olesen
The save area is twice as big and there is no struct return slot. The stack pointer is always 16-byte aligned (after adding the bias). Also eliminate the stack adjustment instructions around calls when the function has a reserved stack frame. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179083 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-07Implement LowerCall_64 for the SPARC v9 64-bit ABI.Jakob Stoklund Olesen
There is still no support for byval arguments (which I don't think are needed) and varargs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178993 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-06Implement LowerReturn_64 for SPARC v9.Jakob Stoklund Olesen
Integer return values are sign or zero extended by the callee, and structs up to 32 bytes in size can be returned in registers. The CC_Sparc64 CallingConv definition is shared between LowerFormalArguments_64 and LowerReturn_64. Function arguments and return values are passed in the same registers. The inreg flag is also used for return values. This is required to handle C functions returning structs containing floats and ints: struct ifp { int i; float f; }; struct ifp f(void); LLVM IR: define inreg { i32, float } @f() { ... ret { i32, float } %retval } The ABI requires that %retval.i is returned in the high bits of %i0 while %retval.f goes in %f1. Without the inreg return value attribute, %retval.i would go in %i0 and %retval.f would go in %f3 which is a more efficient way of returning %multiple values, but it is not ABI compliant for returning C structs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178966 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-06SPARC v9 stack pointer bias.Jakob Stoklund Olesen
64-bit SPARC v9 processes use biased stack and frame pointers, so the current function's stack frame is located at %sp+BIAS .. %fp+BIAS where BIAS = 2047. This makes more local variables directly accessible via [%fp+simm13] addressing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178965 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-06Complete formal arguments for the SPARC v9 64-bit ABI.Jakob Stoklund Olesen
All arguments are formally assigned to stack positions and then promoted to floating point and integer registers. Since there are more floating point registers than integer registers, this can cause situations where floating point arguments are assigned to registers after integer arguments that where assigned to the stack. Use the inreg flag to indicate 32-bit fragments of structs containing both float and int members. The three-way shadowing between stack, integer, and floating point registers requires custom argument lowering. The good news is that return values are passed in the exact same way, and we can share the code. Still missing: - Update LowerReturn to handle structs returned in registers. - LowerCall. - Variadic functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178958 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-04Add SPARC v9 support for select on 64-bit compares.Jakob Stoklund Olesen
This requires v9 cmov instructions using the %xcc flags instead of the %icc flags. Still missing: - Select floats on %xcc flags. - Select i64 on %fcc flags. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178737 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-03Add 64-bit compare + branch for SPARC v9.Jakob Stoklund Olesen
The same compare instruction is used for 32-bit and 64-bit compares. It sets two different sets of flags: icc and xcc. This patch adds a conditional branch instruction using the xcc flags for 64-bit compares. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178621 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-02Add 64-bit load and store instructions.Jakob Stoklund Olesen
There is only a few new instructions, the rest is handled with patterns. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178528 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-02Basic 64-bit ALU operations.Jakob Stoklund Olesen
SPARC v9 extends all ALU instructions to 64 bits, so we simply need to add patterns to use them for both i32 and i64 values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178527 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-02Materialize 64-bit immediates.Jakob Stoklund Olesen
The last resort pattern produces 6 instructions, and there are still opportunities for materializing some immediates in fewer instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178526 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-02Add 64-bit shift instructions.Jakob Stoklund Olesen
SPARC v9 defines new 64-bit shift instructions. The 32-bit shift right instructions are still usable as zero and sign extensions. This adds new F3_Sr and F3_Si instruction formats that probably should be used for the 32-bit shifts as well. They don't really encode an simm13 field. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178525 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-02Add support for 64-bit calling convention.Jakob Stoklund Olesen
This is far from complete, but it is enough to make it possible to write test cases using i64 arguments. Missing features: - Floating point arguments. - Receiving arguments on the stack. - Calls. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178523 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-18Include '.test' suffix in target specific lit configs that need itDavid Blaikie
Apparently my final cleanup to use a relevant suffix for these tests before committing r176831 caused them to stop running since lit wasn't configured to run tests with that suffix in those directories (why don't we just have a global suffix list?). So, add the suffix to the relevant directories & fix the test that has bitrotted over the last week due to my debug info schema changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177315 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-30Use TargetTransformInfo to control switch-to-lookup table transformationHans Wennborg
When the switch-to-lookup tables transform landed in SimplifyCFG, it was pointed out that this could be inappropriate for some targets. Since there was no way at the time for the pass to know anything about the target, an awkward reverse-transform was added in CodeGenPrepare that turned lookup tables back into switches for some targets. This patch uses the new TargetTransformInfo to determine if a switch should be transformed, and removes CodeGenPrepare::ConvertLoadToSwitch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167011 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-19Move load_to_switch.ll to test/CodeGen/SPARC/Hans Wennborg
Because the test invokes llc -march=sparc, it needs to be in a directory which is only run when the sparc target is built. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164211 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-25Continue cleanup of LIT, getting rid of the remaining artifacts from dejagnuEli Bendersky
* Removed test/lib/llvm.exp - it is no longer needed * Deleted the dg.exp reading code from test/lit.cfg. There are no dg.exp files left in the test suite so this code is no longer required. test/lit.cfg is now much shorter and clearer * Removed a lot of duplicate code in lit.local.cfg files that need access to the root configuration, by adding a "root" attribute to the TestingConfig object. This attribute is dynamically computed to provide the same information as was previously provided by the custom getRoot functions. * Documented the config.root attribute in docs/CommandGuide/lit.pod git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153408 91177308-0d34-0410-b5e6-96231b3b80d8
