Brian Gaeke d26074eef1 Missing piece of fix for Bug 333 
llvm-svn: 13362
 2004-05-04 21:41:45 +00:00
Brian Gaeke f2ff5dd442 Correctly mangle function names when they are used as part of a 
constant pool member's name.
This is intended to address Bug 333.

Also, fix an anachronistic usage of "M" as a parameter of type Function *.

Brian Gaeke b3a9a0fcbd Add "Args" optional argument to AbstractInterpreter factory methods, which 
fills in a ToolArgs vector in the AbstractInterpreter if it is set. This
ToolArgs vector is used to pass additional arguments to LLI and/or LLC.
This is intended to address Bug 40.

Also, make -debug-only=toolrunner work for the LLC and CBE
AbstractInterpreters.

Chris Lattner 22df9a59b4 Improve signed division by power of 2 *dramatically* from this: 
div:
        mov %EDX, DWORD PTR [%ESP + 4]
        mov %ECX, 64
        mov %EAX, %EDX
        sar %EDX, 31
        idiv %ECX
        ret

to this:

div:
        mov %EAX, DWORD PTR [%ESP + 4]
        mov %ECX, %EAX
        sar %ECX, 5
        shr %ECX, 26
        mov %EDX, %EAX
        add %EDX, %ECX
        sar %EAX, 6
        ret

Note that the intel compiler is currently making this:

div:
        movl      4(%esp), %edx                                 #3.5
        movl      %edx, %eax                                    #4.14
        sarl      $5, %eax                                      #4.14
        shrl      $26, %eax                                     #4.14
        addl      %edx, %eax                                    #4.14
        sarl      $6, %eax                                      #4.14
        ret                                                     #4.14

Which has one less register->register copy.  (hint hint alkis :)

which case you'll get a null array and zero passed to the profiling function.

 2004-05-01 21:24:39 +00:00
Chris Lattner c49a9a5d76 Stop LiveVariables from using BasicBlocks as part of the mapping, instead 
use MachineBasicBlocks.  To do this, we traverse the Machine CFG instead of
the LLVM CFG, which is also *MUCH* more efficient by having fewer levels of
indirections and mappings.

Chris Lattner 652064e3b8 Fix a major pessimization in the instcombiner. If an allocation instruction 
is only used by a cast, and the casted type is the same size as the original
allocation, it would eliminate the cast by folding it into the allocation.

Unfortunately, it was placing the new allocation instruction right before
the cast, which could pull (for example) alloca instructions into the body
of a function.  This turns statically allocatable allocas into expensive
dynamically allocated allocas, which is bad bad bad.

This fixes the problem by placing the new allocation instruction at the same
place the old one was, duh. :)

Brian Gaeke 4390e4a7fc Make RequiresFPRegKill() take a MachineBasicBlock arg. 
In InsertFPRegKills(), just check the MachineBasicBlock for successors
instead of its corresponding BasicBlock.

 2004-04-28 04:45:55 +00:00
Brian Gaeke 33ff118407 In InsertFPRegKills(), use the machine-CFG itself rather than the

Brian Gaeke 03cac379bd Fix file header comments and include guards -- many files have been moved or

 2004-04-25 06:32:16 +00:00
Brian Gaeke f70544c583 Add MRegisterInfo subclass for the SparcV9 target (containing only stub 
functions for now). This automatically turns on the printing of machine
registers using their own real names, instead of goofy things like %mreg(42),
and allows us to migrate code incrementally to the new interface as we see fit.

The register file description it uses is hand-written, so that the register
numbers will match the ones that the SparcV9 target already uses.
Perhaps someday we'll tablegen it.
