|
||
| GCC and Clang are architecturally different, which leads to subtle | ||
| issues for code that's invalid but clearly dead. This can happen with | ||
| code that emulates polymorphism with the preprocessor and sizeof. | ||
|
|
||
| GCC will perform semantic analysis after early inlining and dead code | ||
| elimination, so it will not warn on invalid code that's dead. Clang | ||
| strictly performs optimizations after semantic analysis, so it will warn | ||
| for dead code. | ||
|
|
||
| Neither Clang nor GCC like this very much with -m32: | ||
|
|
||
| long long ret; | ||
| asm ("movb $5, %0" : "=q" (ret)); | ||
|
|
||
| However, GCC can tolerate this variant: | ||
|
|
||
| long long ret; | ||
| switch (sizeof(ret)) { | ||
| case 1: | ||
| asm ("movb $5, %0" : "=q" (ret)); | ||
| break; | ||
| case 8:; | ||
| } | ||
|
|
||
| Clang, on the other hand, won't accept that because it validates the | ||
| inline asm for the '1' case *before* the optimisation phase where it | ||
| realises that it wouldn't have to emit it anyway. | ||
|
|
||
| If LLVM (Clang's "back end") fails such as during instruction selection | ||
| or register allocation, it cannot provide accurate diagnostics | ||
| (warnings/errors) that contain line information, as the AST has been | ||
| discarded from memory at that point. | ||
|
|
||
| While there have been early discussions about having C/C++ specific | ||
| language optimizations in Clang via the use of MLIR, which would enable | ||
| such earlier optimizations, such work is not scoped and likely a | ||
| multi-year endeavor. | ||
|
|
||
| We also don't want to swap the use of "=q" with "=r". For 64b, it | ||
| doesn't matter. For 32b, it's possible that a 32b register without a 8b | ||
| lower alias (i.e. ESI, EDI, EBP) is selected which the assembler will | ||
| then reject. | ||
|
|
||
| With this, Clang can finally build an i386 defconfig. | ||

| Part of the commit message is stolen from David, and part from Linus. | ||
| Shall I resend with David's authorship and | ||

| ??? | ||
|
|
||
| I don't really care, I just don't really want to carry this out of tree | ||
