* Add an option that allows one to "decode" the LSDA.Bill Wendling2011-06-177-17/+395
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The LSDA is a bit difficult for the non-initiated to read. Even with comments, it's not always clear what's going on. This wraps the ASM streamer in a class that retains the LSDA and then emits a human-readable description of what's going on in it. So instead of having to make sense of: Lexception1: .byte 255 .byte 155 .byte 168 .space 1 .byte 3 .byte 26 Lset0 = Ltmp7-Leh_func_begin1 .long Lset0 Lset1 = Ltmp812-Ltmp7 .long Lset1 Lset2 = Ltmp913-Leh_func_begin1 .long Lset2 .byte 3 Lset3 = Ltmp812-Leh_func_begin1 .long Lset3 Lset4 = Leh_func_end1-Ltmp812 .long Lset4 .long 0 .byte 0 .byte 1 .byte 0 .byte 2 .byte 125 .long __ZTIi@GOTPCREL+4 .long __ZTIPKc@GOTPCREL+4 you can read this instead: ## Exception Handling Table: Lexception1 ## @LPStart Encoding: omit ## @TType Encoding: indirect pcrel sdata4 ## @TType Base: 40 bytes ## @CallSite Encoding: udata4 ## @Action Table Size: 26 bytes ## Action 1: ## A throw between Ltmp7 and Ltmp812 jumps to Ltmp913 on an exception. ## For type(s): __ZTIi@GOTPCREL+4 __ZTIPKc@GOTPCREL+4 ## Action 2: ## A throw between Ltmp812 and Leh_func_end1 does not have a landing pad. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133286 91177308-0d34-0410-b5e6-96231b3b80d8

* PTX: Adjust rounding modesJustin Holewinski2011-06-177-45/+60
| | | | | | | | | | | | | | | * 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.

| | | | | | | | | | | Also switch the return type to ArrayRef<unsigned> which works out nicely for ARM's implementation of this function because of the clever ArrayRef constructors.
