From e134202611a50b358c147c92bfb8a7f443030b8b Mon Sep 17 00:00:00 2001 From: Kimplul Date: Mon, 8 Jul 2024 17:43:59 +0300 Subject: fix LLVM + Anything extern is right out as LLVM doesn't produce correct code for them. Maybe if I added some extra attributes but I'm skeptical. Replaced with static variables and getters/setters. + Inline ASM is apparently a bit buggy, so use an assembly stub when jumping to init. + Minimize work done in main() to minimize chance of LLVM doing something silly. Still not 100% certain that I shouldn't just write the main() as an assembly stub in arch/riscv64 to be absolutely sure everything works as intended. + Make .kernel.start section SHF_ALLOC, otherwise lld complains about pc-relative addressing Probably some other stuff as well that I'm forgetting right now. But at least with LLVM14 LTO seems to work, which is pretty cool? --- src/debug.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/debug.c') diff --git a/src/debug.c b/src/debug.c index 567911b..d87588d 100644 --- a/src/debug.c +++ b/src/debug.c @@ -392,7 +392,7 @@ static size_t __print_prefix(size_t base) case 16: return __puts("0x"); case 8: return __puts("0"); case 2: return __puts("0b"); - default: + default: break; } return 0; -- cgit v1.3
