439e61cc1f update command guide to have --tool-args 
llvm-svn: 13359
 2004-05-04 21:13:35 +00:00

433b49b796 Add --tool-args flag which lets you pass arguments to llc or lli. 
This is intended to address Bug 40.

28d81c4d0d 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 *.

ba26360c7e 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.

dac54ebbee 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 :)

769668c09a 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.
