2006-05-03Suck block address tracking out of targets into the JIT Emitter. ThisChris Lattner
simplifies the MachineCodeEmitter interface just a little bit and makes BasicBlocks work like constant pools and jump tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28082 91177308-0d34-0410-b5e6-96231b3b80d8

2006-05-03Change the BasicBlockAddrs map to be a vector, indexed by MBB number.Chris Lattner

2006-05-02Several related changes:Chris Lattner
1. Change several methods in the MachineCodeEmitter class to be pure virtual. 2. Suck emitConstantPool/initJumpTableInfo into startFunction, removing them from the MachineCodeEmitter interface, and reducing the amount of target- specific code. 3. Change the JITEmitter so that it allocates constantpools and jump tables *right* next to the functions that they belong to, instead of in a separate pool of memory. This makes all memory for a function be contiguous, and means the JITEmitter only tracks one block of memory now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28065 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-02Fix a purely hypothetical problem (for now): emitWord emits in the hostChris Lattner
byte format. This doesn't work when using the code emitter in a cross target environment. Since the code emitter is only really used by the JIT, this isn't a current problem, but if we ever start emitting .o files, it would be. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28060 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-02Refactor the machine code emitter interface to pull the pointers for the currentChris Lattner
code emission location into the base class, instead of being in the derived classes. This change means that low-level methods like emitByte/emitWord now are no longer virtual (yaay for speed), and we now have a framework to support growable code segments. This implements feature request #1 of PR469. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28059 91177308-0d34-0410-b5e6-96231b3b80d8

2006-04-22JumpTable support! What this represents is working asm and jit support forNate Begeman
x86 and ppc for 100% dense switch statements when relocations are non-PIC. This support will be extended and enhanced in the coming days to support PIC, and less dense forms of jump tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27947 91177308-0d34-0410-b5e6-96231b3b80d8

2006-02-22- Added option -relocation-model to set relocation model. Valid values ↵Evan Cheng
include static, pic, dynamic-no-pic, and default. PPC and x86 default is dynamic-no-pic for Darwin, pic for others. - Removed options -enable-pic and -ppc-static. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26315 91177308-0d34-0410-b5e6-96231b3b80d8

2006-02-01- Use xor to clear integer registers (set R, 0).Evan Cheng

2005-07-06First round of support for doing scalar FP using the SSE2 ISA extension andNate Begeman
XMM registers. There are many known deficiencies and fixmes, which will be addressed ASAP. The major benefit of this work is that it will allow the LLVM register allocator to allocate FP registers across basic blocks. The x86 backend will still default to x87 style FP. To enable this work, you must pass -enable-sse-scalar-fp and either -sse2 or -sse3 to llc. An example before and after would be for: double foo(double *P) { double Sum = 0; int i; for (i = 0; i < 1000; ++i) Sum += P[i]; return Sum; } The inner loop looks like the following: x87: .LBB_foo_1: # no_exit fldl (%esp) faddl (%eax,%ecx,8) fstpl (%esp) incl %ecx cmpl $1000, %ecx #FP_REG_KILL jne .LBB_foo_1 # no_exit SSE2: addsd (%eax,%ecx,8), %xmm0 incl %ecx cmpl $1000, %ecx #FP_REG_KILL jne .LBB_foo_1 # no_exit git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22340 91177308-0d34-0410-b5e6-96231b3b80d8
