2005-03-15This mega patch converts us from using Function::a{iterator|begin|end} toChris Lattner
using Function::arg_{iterator|begin|end}. Likewise Module::g* -> Module::global_*. This patch is contributed by Gabor Greif, thanks! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20597 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-08Make sure to remove all dead type names from the symbol table, not justChris Lattner
struct types. This fixes Regression/CodeGen/CBackend/2005-03-08-RecursiveTypeCrash.ll, a crash on Java output that Alkis reported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20519 91177308-0d34-0410-b5e6-96231b3b80d8

2005-03-03Print -X like this:Chris Lattner
double test(double l1_X) { return (-l1_X); } instead of like this: double test(double l1_X) { return (-0x0p+0 - l1_X); } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20423 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-03Do not lower malloc's to pass "sizeof" expressions like this:Chris Lattner
ltmp_0_7 = malloc(((unsigned )(&(((signed char (*)[784])/*NULL*/0)[1u])))); Instead, just emit the literal constant, like this: ltmp_0_7 = malloc(784u); This works around a bug in ICC 8.1 compiling the CBE generated code. :-( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20415 91177308-0d34-0410-b5e6-96231b3b80d8

2005-02-15Fix volatile load/store of pointers. Consider this testcase:Chris Lattner
void %test(int** %P) { %A = volatile load int** %P ret void } void %test2(int*** %Q) { %P = load int*** %Q volatile store int** %P, int*** %Q ret void } instead of emitting: void test(int **l1_P) { int *l2_A; l2_A = (int **((volatile int **)l1_P)); return; } void test2(int ***l2_Q) { int **l1_P; l1_P = *l2_Q; *((volatile int ***)l2_Q) = l1_P; return; } ... which is loading/storing volatile pointers, not through volatile pointers, emit this (which is right): void test(int **l1_P) { int *l3_A; l3_A = *((int * volatile*)l1_P); return; } void test2(int ***l2_Q) { int **l1_P; l1_P = *l2_Q; *((int ** volatile*)l2_Q) = l1_P; return; } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20191 91177308-0d34-0410-b5e6-96231b3b80d8

2004-10-25Modified switch generation so that only the phi values associated with theJohn Criswell
destination basic block are copied. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17212 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-20Small performance improvement in generated C code:John Criswell
Instead of unconditionally copying all phi node values into temporaries for all successor blocks, generate code that will determine what successor block will be called and then copy only those phi node values needed by the successor block. This seems to cut down namd execution time from being 8% higher than GCC to 4% higher than GCC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17144 91177308-0d34-0410-b5e6-96231b3b80d8

2004-10-17The first hunk corrects a bug when printing undef null values. We would printChris Lattner
0->field, which is illegal. Now we print ((foo*)0)->field. The second hunk is an optimization to not print undefined phi values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17094 91177308-0d34-0410-b5e6-96231b3b80d8
