Two more improvements for null pointer handling: storing a null pointer
...
and passing a null pointer into a function.
For this testcase:
void %test(int** %X) {
store int* null, int** %X
call void %test(int** null)
ret void
}
we now generate this:
test:
sub %ESP, 12
mov %EAX, DWORD PTR [%ESP + 16]
mov DWORD PTR [%EAX], 0
mov DWORD PTR [%ESP], 0
call test
add %ESP, 12
ret
instead of this:
test:
sub %ESP, 12
mov %EAX, DWORD PTR [%ESP + 16]
mov %ECX, 0
mov DWORD PTR [%EAX], %ECX
mov %EAX, 0
mov DWORD PTR [%ESP], %EAX
call test
add %ESP, 12
ret

Second half of my fixed-sized-alloca patch. This folds the LEA to compute
...
the alloca address into common operations like loads/stores.
In a simple testcase like this (which is just designed to excersize the
alloca A, nothing more):
int %test(int %X, bool %C) {
%A = alloca int
store int %X, int* %A
store int* %A, int** %G
br bool %C, label %T, label %F
T:
call int %test(int 1, bool false)
%V = load int* %A
ret int %V
F:
call int %test(int 123, bool true)
%V2 = load int* %A
ret int %V2
}
We now generate:
test:
sub %ESP, 12
mov %EAX, DWORD PTR [%ESP + 16]
mov %CL, BYTE PTR [%ESP + 20]
*** mov DWORD PTR [%ESP + 8], %EAX
mov %EAX, OFFSET G
lea %EDX, DWORD PTR [%ESP + 8]
mov DWORD PTR [%EAX], %EDX
test %CL, %CL
je .LBB2 # PC rel: F
.LBB1: # T
mov DWORD PTR [%ESP], 1
mov DWORD PTR [%ESP + 4], 0
call test
*** mov %EAX, DWORD PTR [%ESP + 8]
add %ESP, 12
ret
.LBB2: # F
mov DWORD PTR [%ESP], 123
mov DWORD PTR [%ESP + 4], 1
call test
*** mov %EAX, DWORD PTR [%ESP + 8]
add %ESP, 12
ret
Instead of:
test:
sub %ESP, 20
mov %EAX, DWORD PTR [%ESP + 24]
mov %CL, BYTE PTR [%ESP + 28]
*** lea %EDX, DWORD PTR [%ESP + 16]
*** mov DWORD PTR [%EDX], %EAX
mov %EAX, OFFSET G
mov DWORD PTR [%EAX], %EDX
test %CL, %CL
*** mov DWORD PTR [%ESP + 12], %EDX

Substantially improve code generation for address exposed locals (aka fixed
...
sized allocas in the entry block). Instead of generating code like this:
entry:
reg1024 = ESP+1234
... (much later)
*reg1024 = 17
Generate code that looks like this:
entry:
(no code generated)
... (much later)
t = ESP+1234
*t = 17
The advantage being that we DRAMATICALLY reduce the register pressure for these
silly temporaries (they were all being spilled to the stack, resulting in very
silly code). This is actually a manual implementation of rematerialization :)
I have a patch to fold the alloca address computation into loads & stores, which
will make this much better still, but just getting this right took way too much time
and I'm sleepy.

Generate substantially better code when there are a limited number of exits
...
from the extracted region. If the return has 0 or 1 exit blocks, the new
function returns void. If it has 2 exits, it returns bool, otherwise it
returns a ushort as before.
This allows us to use a conditional branch instruction when there are two
exit blocks, as often happens during block extraction.

Two minor improvements:
...
1. Get rid of the silly abort block. When doing bb extraction, we get one
abort block for every block extracted, which is kinda annoying.
2. If the switch ends up having a single destination, turn it into an
unconditional branch.
I would like to add support for conditional branches, but to do this we will
want to have the function return a bool instead of a ushort.

Also of note, this patch adds a -extract-bbs option to bugpoint which can be used
to debug the block extractor. (hint hint Misha :)

Allow the user to set the LLVMINTERP environment variable as a workaround, for

This is intended to address Bug 289.
Also, emit the traditional syntax ${1+"$@"} for passing all of a shell script's
args to a subprocess. If you have arguments that have spaces in them, $* will
not preserve the quoting (i.e., the quoted string "foo bar" as an argument will
end up as two arguments "foo" "bar" to lli.)

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.

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.

add %EDX, %ECX

Note that the intel compiler is currently making this:

movl %edx, %eax #4.14
sarl $5, %eax #4.14
shrl $26, %eax #4.14

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. :)

Implement a fixme. The helps loops that have induction variables of different

types in them. Instead of creating an induction variable for all types, it
creates a single induction variable and casts to the other sizes. This generates
this code:
no_exit: ; preds = %entry, %no_exit
%indvar = phi uint [ %indvar.next, %no_exit ], [ 0, %entry ] ; <uint> [#uses=4]
*** %j.0.0 = cast uint %indvar to short ; <short> [#uses=1]
%indvar = cast uint %indvar to int ; <int> [#uses=1]
%tmp.7 = getelementptr short* %P, uint %indvar ; <short*> [#uses=1]
store short %j.0.0, short* %tmp.7
%inc.0 = add int %indvar, 1 ; <int> [#uses=2]
%tmp.2 = setlt int %inc.0, %N ; <bool> [#uses=1]
%indvar.next = add uint %indvar, 1 ; <uint> [#uses=1]
br bool %tmp.2, label %no_exit, label %loopexit
instead of:
no_exit: ; preds = %entry, %no_exit
%indvar = phi ushort [ %indvar.next, %no_exit ], [ 0, %entry ] ; <ushort> [#uses=2]
*** %indvar = phi uint [ %indvar.next, %no_exit ], [ 0, %entry ] ; <uint> [#uses=3]
%indvar = cast uint %indvar to int ; <int> [#uses=1]
%indvar = cast ushort %indvar to short ; <short> [#uses=1]
%tmp.7 = getelementptr short* %P, uint %indvar ; <short*> [#uses=1]
store short %indvar, short* %tmp.7
%inc.0 = add int %indvar, 1 ; <int> [#uses=2]
%tmp.2 = setlt int %inc.0, %N ; <bool> [#uses=1]
%indvar.next = add uint %indvar, 1
*** %indvar.next = add ushort %indvar, 1
br bool %tmp.2, label %no_exit, label %loopexit
This is an improvement in register pressure, but probably doesn't happen that
often.
The more important fix will be to get rid of the redundant add.
