rename run to runFunction
Genericize the runFunction code a little bit, though it still stinks

Alkis Evlogimenos 2e8c984c58 Improve debugging output when choosing a register to spill. 
llvm-svn: 10604
 2003-12-24 18:53:31 +00:00
Alkis Evlogimenos eeea81483f Do a separate pass to compute spill weights because doing it inline 
with live intervals was missing registers that were used before they
were defined (in the arbitrary order live intervals numbers
instructions).

Chris Lattner 87c593b882 Right, fix the problem with invoke instructions, not just call instructions 
llvm-svn: 10599
 2003-12-23 22:18:36 +00:00
Chris Lattner 601415ed84 Do not delete the type holder until after the call instruction has been 
constructed!

Alkis Evlogimenos 7d7d7e89d4 Change the way free regusters are computed and perform better 
allocation in the presence of preallocated intervals.

Chris Lattner 7e755e443f More minor non-functional changes. This now computes the exit condition, though 
it doesn't do anything with it.

llvm-svn: 10586
 2003-12-22 23:49:36 +00:00
John Criswell bd10d09b07 Reverted back to revision 1.11. The previous fix doesn't really fix 
anything; it just causes the bug to go dormant.

Chris Lattner a02d5aa6ce Don't mind me, I'm just refactoring away. This patch makes room for LFTR, but 
contains no functionality changes.

Alkis Evlogimenos 690e1b8de2 Remove verifyIntervals() since it doesn't actually work right now. 
llvm-svn: 10570
 2003-12-21 20:41:26 +00:00
Alkis Evlogimenos 2665d9c6f9 Change weight into a float so that we can take into account the 
nesting level when computing it. Right now the allocator uses:

    w = sum_over_defs_uses( 10 ^ nesting level );

llvm-svn: 10569
 2003-12-21 20:19:10 +00:00
Alkis Evlogimenos 2103574b32 Move FP_REG_KILL closer to the return instruction. 
llvm-svn: 10567
 2003-12-21 16:47:43 +00:00
Alkis Evlogimenos c09b77ea35 Add support for inactive intervals. This effectively reuses registers 
for live ranges that fall into assigned registers' holes.

llvm-svn: 10566
 2003-12-21 05:43:40 +00:00
John Criswell d8c7a7fbaa Fix PR#193. 
Modified ReadArchiveBuffer() so that it dynamically allocates the
std::string object used to hold the bytecode object file's name.  This is
necessary because it is passed by reference to the new Module that is
allocated to represent the bytecode object, and previously we were
using a std::string that disappeared on function exit.

llvm-svn: 10565
 2003-12-20 22:37:29 +00:00
Alkis Evlogimenos 27437e3318 Move FP_REG_KILL closer to the actual branch instruction. 
llvm-svn: 10563
 2003-12-20 17:28:15 +00:00
Alkis Evlogimenos 68cff6bf4d Remove floating point killer pass. This is now implemented in the 
instruction selector by adding a new pseudo-instruction
FP_REG_KILL. This instruction implicitly defines all x86 fp registers
and is a terminator so that passes which add machine code at the end
of basic blocks (like phi elimination) do not add instructions between
it and the branch or return instruction.

Chris Lattner 4cbb97bfdd Add a new target-independent machine code freeing pass 
llvm-svn: 10560
 2003-12-20 10:20:58 +00:00
Chris Lattner 452597611f Finally, _actually delete the machine code_ for a function, after it has 
been emitted.  Also, since the FPK pass is causing memory access violations,
disable it.

llvm-svn: 10554
 2003-12-20 09:17:40 +00:00
Chris Lattner 9a3478e022 * Finegrainify namespacification 
* Move sparc specific code out of generic code
* Eliminate the getOffset() method which made INVALID_FRAME_OFFSET
  necessary, which made pulling in MAX_INT as a sentinal necessary.

Chris Lattner 9bcae072d1 Cleanup the JIT as per PR176. This renames the VM class to JIT, and merges the 
VM.cpp and JIT.cpp files into JIT.cpp.  This also splits some nasty code out
into TargetSelect.cpp so that people hopefully won't notice it.  :)
