John Criswell 2af0fd3ca8 Don't call getForwardedType() twice, as recommended by Chris.

Chris Lattner 6aee736d1b Use the new commandline flag to allow us to call bugpoint like this: 
bugpoint ... --tool-args -enable-correct-eh-support -regalloc=linearscan --args -- -foo

So that tool-args option gets the -enable-correct-eh-support -regalloc=linearscan flags instead of bugpoint.

John Criswell f6709bc579 Fix for PR#330. 
When looking at getelementptr instructions, make sure to use a forwarded
type.  We want to do this because a DerivedType may drop its uses and then
refine its users, who may then use another user who hasn't been refined yet.
By getting the forwarded type, we always ensure that we're looking at a
Type that isn't in a halfway refined state.

Now, I should be able to put this stuff in PATypeHandle, but it doesn't work
for some reason.  This should do for now.

Chris Lattner 991425ae70 numeric_limits::infinity() apparently does not work on all systems. As a 
workaround, use the C HUGE_VAL macro instead.

Alkis Evlogimenos 4c4497e834 Fix for gcc3.4: invalid use of forward delacred class on line 93

Brian Gaeke e330adf842 Move the stuff that fixes the size, orientation & fonts of graphs to 
the debugging functions that call "dot". These fixed settings have
various problems: for example, the fixed size that is set in the graph
traits classes is not appropriate for turning the dot file into a PNG,
and if TrueType font rendering is being used, the 'Courier' TrueType font
may not be installed. It seems easy enough to specify these things on the
command line, anyhow.

 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.

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 *.

 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 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 :)
