| | * When testing builtin functions, prevent constant propagationXavier Leroy2019-07-174-28/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that some builtin functions have known semantics, constant propagation can happen in this test. This defeats the purpose, which is to check that the correct processor instructions are generated. To prevent this constant propagation, we move the initialized variables to global scope. Since they are not "const", their values are not known to the optimizer.
| | * Extended asm: print register names according to their typesXavier Leroy2019-06-171-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When printing an extended asm code fragment, placeholders %n are replaced by register names. Currently we ignore the fact that some assemblers use different register names depending on the width of the data that resides in the register. For example, x86_64 uses %rax for a 64-bit quantity and %eax for a 32-bit quantity, but CompCert always prints %rax in extended asm statements. This is problematic if we want to use 32-bit integer instructions in extended asm, e.g. int x, y; asm("addl %1, %0", "=r"(x), "r"(y)); produces addl %rax, %rdx which is syntactically incorrect. Another example is ARM FP registers: D0 is a double-precision float, but S0 is a single-precision float. This commit partially solves this issue by taking into account the Cminor type of the asm parameter when printing the corresponding register. Continuing the previous example, int x, y; asm("addl %1, %0", "=r"(x), "r"(y)); now produces addl %eax, %edx This is not perfect yet: we use Cminor types, because this is all we have at hand, and not source C types, hence "char" and "short" parameters are still printed like "int" parameters, which is not good for x86. (I.e. we produce %eax where GCC might have produced %al or %ax.) We'll leave this issue open.
| | * Perform constant propagation and strength reduction on conditional movesXavier Leroy2019-06-171-0/+20
| | | | | | | | | | | | | | | A conditional move whose condition is statically known becomes a regular move. Otherwise, the condition can sometimes be simplified by strength reduction.
| | * If-conversion optimizationXavier Leroy2019-06-063-1/+156
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extends the instruction selection pass with an if-conversion optimization: some if/then/else statements are converted into "select" operations, which in turn can be compiled down to branchless instruction sequences if the target architecture supports them. The statements that are converted are of the form if (cond) { x = a1; } else { x = a2; } if (cond) { x = a1; } if (cond) { /*skip*/; } else { x = a2; } where a1, a2 are "safe" expressions, containing no operations that can fail at run-time, such as memory loads or integer divisions. A heuristic in backend/Selectionaux.ml controls when the optimization occurs, depending on command-line flags and the complexity of the "then" and "else" branches.
