Brian Gaeke d26074eef1 Missing piece of fix for Bug 333 
llvm-svn: 13362
 2004-05-04 21:41:45 +00:00
Brian Gaeke e307f8a791 Bugs fixed 
llvm-svn: 13360
 2004-05-04 21:22:57 +00:00
Brian Gaeke 48ef3f0fa1 update command guide to have --tool-args 
llvm-svn: 13359
 2004-05-04 21:13:35 +00:00
Brian Gaeke 4a278f0b1b Add --tool-args flag which lets you pass arguments to llc or lli. 
This is intended to address Bug 40.

llvm-svn: 13358
 2004-05-04 21:09:16 +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 *.

llvm-svn: 13357
 2004-05-04 21:09:02 +00:00
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 c6f601310f Remove unneeded check

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 :)

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.
