2004-10-17Rewrite support for cast uint -> FP. In particular, we used to compile this:Chris Lattner
double %test(uint %X) { %tmp.1 = cast uint %X to double ; <double> [#uses=1] ret double %tmp.1 } into: test: sub %ESP, 8 mov %EAX, DWORD PTR [%ESP + 12] mov %ECX, 0 mov DWORD PTR [%ESP], %EAX mov DWORD PTR [%ESP + 4], %ECX fild QWORD PTR [%ESP] add %ESP, 8 ret ... which basically zero extends to 8 bytes, then does an fild for an 8-byte signed int. Now we generate this: test: sub %ESP, 4 mov %EAX, DWORD PTR [%ESP + 8] mov DWORD PTR [%ESP], %EAX fild DWORD PTR [%ESP] shr %EAX, 31 fadd DWORD PTR [.CPItest_0 + 4*%EAX] add %ESP, 4 ret .section .rodata .align 4 .CPItest_0: .quad 5728578726015270912 This does a 32-bit signed integer load, then adds in an offset if the sign bit of the integer was set. It turns out that this is substantially faster than the preceeding sequence. Consider this testcase: unsigned a[2]={1,2}; volatile double G; void main() { int i; for (i=0; i<100000000; ++i ) G += a[i&1]; } On zion (a P4 Xeon, 3Ghz), this patch speeds up the testcase from 2.140s to 0.94s. On apoc, an athlon MP 2100+, this patch speeds up the testcase from 1.72s to 1.34s. Note that the program takes 2.5s/1.97s on zion/apoc with GCC 3.3 -O3 -fomit-frame-pointer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17083 91177308-0d34-0410-b5e6-96231b3b80d8

index reg and scale git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17081 91177308-0d34-0410-b5e6-96231b3b80d8

%X = and Y, constantint %Z = setcc %X, 0 instead of emitting: and %EAX, 3 test %EAX, %EAX je .LBBfoo2_2 # UnifiedReturnBlock We now emit: test %EAX, 3 je .LBBfoo2_2 # UnifiedReturnBlock This triggers 581 times on 176.gcc for example. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17080 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-17All of these labels are off by one now that the unreachable instruction existsChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17079 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-17Implement bitfield insert by recognizing the following pattern:Nate Begeman
1. optional shift left 2. and x, immX 3. and y, immY 4. or z, x, y ==> rlwimi z, x, y, shift, mask begin, mask end where immX == ~immY and immX is a run of set bits. This transformation fires 32 times on voronoi, once on espresso, and probably several dozen times on external benchmarks such as gcc. To put this in terms of actual code generated for struct B { unsigned a : 3; unsigned b : 2; }; void storeA (struct B *b, int v) { b->a = v;} void storeB (struct B *b, int v) { b->b = v;} Old: _storeA: rlwinm r2, r4, 0, 29, 31 lwz r4, 0(r3) rlwinm r4, r4, 0, 0, 28 or r2, r4, r2 stw r2, 0(r3) blr _storeB: rlwinm r2, r4, 3, 0, 28 rlwinm r2, r2, 0, 27, 28 lwz r4, 0(r3) rlwinm r4, r4, 0, 29, 26 or r2, r2, r4 stw r2, 0(r3) blr New: _storeA: lwz r2, 0(r3) rlwimi r2, r4, 0, 29, 31 stw r2, 0(r3) blr _storeB: lwz r2, 0(r3) rlwimi r2, r4, 3, 27, 28 stw r2, 0(r3) blr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17078 91177308-0d34-0410-b5e6-96231b3b80d8

that we undefine the macro before using its name in the definition. This can happen on Linux if _GNU_SOURCE is defined. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17071 91177308-0d34-0410-b5e6-96231b3b80d8

2004-10-16Finally fix one of the oldest FIXMEs in the PowerPC backend: correctlyNate Begeman
flag rotate left word immediate then mask insert (rlwimi) as a two-address instruction, and update the ISel usage of the instruction accordingly. This will allow us to properly schedule rlwimi, and use it to efficiently codegen bitfield operations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17068 91177308-0d34-0410-b5e6-96231b3b80d8
