2011-09-28	PTX: MC-ize the PTX back-end (patch 1 of N)	Justin Holewinski
	Lay some groundwork for converting to MC-based asm printer. This is the first of probably many patches to bring the back-end back up-to-date with all of the recent MC changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140697 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-22	PTX: fixup test cases for register changes	Justin Holewinski

2011-06-23	PTX: Always use registers for return values, but use .param space for device	Justin Holewinski
	parameters if SM >= 2.0 - Update test cases to be more robust against register allocation changes - Bump up the number of registers to 128 per type - Include Python script to re-generate register file with any number of registers git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133736 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-17	PTX: Adjust rounding modes	Justin Holewinski
	* rounding modes for fp add, mul, sub now use .rn * float -> int rounding correctly uses .rzi not .rni * 32bit fdiv for sm13 uses div.rn (instead of div.approx) * 32bit fdiv for sm10 now uses div (instead of div.approx) Approx is not IEEE 754 compatible (and should be optionally set by a flag to the backend instead). The .rn rounding modifier is the PTX default anyway, but it's better to be explicit. All these modifiers should be available by using __fmul_rz functions for example, but support will need to be added for this in the backend.

2011-04-20	PTX: Add intrinsics to list of built-in intrinsics, which allows them to be	Justin Holewinski
	used by Clang. To help Clang integration, the PTX target has been split into two targets: ptx32 and ptx64, depending on the desired pointer size. - Add GCCBuiltin class to all intrinsics - Split PTX target into ptx32 and ptx64 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129851 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-02	Extend initial support for primitive types in PTX backend	Che-Liang Chiou
	- Allow i16, i32, i64, float, and double types, using the native .u16, .u32, .u64, .f32, and .f64 PTX types. - Allow loading/storing of all primitive types. - Allow primitive types to be passed as parameters. - Allow selection of PTX Version and Shader Model as sub-target attributes. - Merge integer/floating-point test cases for load/store. - Use .u32 instead of .s32 to conform to output from NVidia nvcc compiler.

2011-02-28	Add preliminary support for .f32 in the PTX backend.	Che-Liang Chiou
	- Add appropriate TableGen patterns for fadd, fsub, fmul. - Add .f32 as the PTX type for the LLVM float type. - Allow parameters, return values, and global variable declarations to accept the float type. - Add appropriate test cases.
