Andrew Lenharth 27cf4eb1c7 Ah the problems you have to fix when you stray from the One True Way (TM)

Chris Lattner cf08c21f2c Reduce the amount of searching this assertion does. On a testcase of mine, 
this reduces the time for -simplifycfg in a debug build from 106s to 14.82s

Chris Lattner 5e166a5f3e Fix a bugpoint crash that JeffC noticed, looking like this: 
*** Attempting to perform final cleanups: Final cleanups failed.  Sorry. :(  Ple
ase report a bug!

<llc>llc.exe: bytecode didn't read correctly.
llc.exe: bytecode didn't read correctly.
<crash>
Assertion failed: M && "You can't write a null module!!", file c:\llvm\lib\bytec
ode\writer\writer.cpp, line 1094


The fact that llc bombed (in this case) is ok, but bugpoint shouldn't crash after this.

Chris Lattner a474313902 Fix a bug in the 'store fpimm, ptr' -> 'store intimm, ptr' handling code. 
Changing 'op' here caused us to not enter the store into a map, causing
reemission of the code!!  In practice, a simple loop like this:

no_exit:                ; preds = %no_exit, %entry
        %indvar = phi uint [ %indvar.next, %no_exit ], [ 0, %entry ]            ; <uint> [#uses=3]
        %tmp.4 = getelementptr "complex long double"* %P, uint %indvar, uint 0          ; <double*> [#uses=1]
        store double 0.000000e+00, double* %tmp.4
        %indvar.next = add uint %indvar, 1              ; <uint> [#uses=2]
        %exitcond = seteq uint %indvar.next, %N         ; <bool> [#uses=1]
        br bool %exitcond, label %return, label %no_exit

was being code gen'd to:

.LBBtest_1:     # no_exit
        movl %edx, %esi
        shll $4, %esi
        movl $0, 4(%eax,%esi)
        movl $0, (%eax,%esi)
        incl %edx
        movl $0, (%eax,%esi)
        movl $0, 4(%eax,%esi)
        cmpl %ecx, %edx
        jne .LBBtest_1  # no_exit

Note that we are doing 4 32-bit stores instead of 2.  Now we generate:

.LBBtest_1:     # no_exit
        movl %edx, %esi
        incl %esi
        shll $4, %edx
        movl $0, (%eax,%edx)
        movl $0, 4(%eax,%edx)
        cmpl %ecx, %esi
        movl %esi, %edx
        jne .LBBtest_1  # no_exit

This is much happier, though it would be even better if the increment of ESI
was scheduled after the compare :-/

llvm-svn: 20248
 2005-02-19 17:07:48 +00:00
Chris Lattner a94f9ffd0e Adjust this test to pass after recent CFE changes. We now generate: 
%XX = global int cast (int* getelementptr ([2 x int]* getelementptr (%struct.S* null, int 0, uint 0), int 0, int 1) to int)

which is the literal translation of the testcase :)
