IT BETTER SHOULD NOT, NEVER! __divdi3 (37 instructions) calls __udivmoddi4 (254 instructions) __moddi3 (51 instructions) calls __udivmoddi4 (254 instructions) __divmoddi4 (36 instructions) calls __divdi3 (37 instructions) which calls __udivmoddi4 (254 instructions) __udivdi3 (8 instructions) calls __udivmoddi4 (254 instructions) __umoddi3 (33...

...ward Hinnant is NO MORE with LLVM: who is the CURRENT code owner and reviewer for the builtins library, especially for x86? I'm asking this SIMPLE question now for the 3rd time! I also have __udivmoddi3: adding the pointer to the remainder as argument and 4 more instructions will turn it into __udivmoddi4. Compiling them with MSVC is of course easy to achieve: remove the MASM/ML statements, put the assembler source inside an __asm block, and add a function definition with __declspec(naked) But then someone will have to find new filenames; I'd prefer to leave them as *.ASM, so they can be added...

This fixes a long standing issue where it was not possible to do "make usr/klibc/arch/x86_64/longjmp.o" in the kernel. The principle is that all .o files to be part of klibc are listed with klib-y. For each directory a klib.list file is made that specify all .o file and the final AR then adds all .o files to create libc.a. This patch introduce the infrastructure and converts x86_64 to
