Andrei Borzenkov	a0bf403f66	asm-tests/i386-pc: Check that movl is 5 bytes. ... LLVM 3.9 now emits short form of jump instructions, but it is still using 32 bit addresses for some movl instructions. Fortunately it was caught early: clang ... boot/i386/pc/boot.S clang -cc1as: fatal error: error in backend: invalid .org offset '440' (at offset '441') Add additional check to catch it during configure run and force -no-integrated-as. Closes: 49200 More details in https://lists.gnu.org/archive/html/grub-devel/2015-02/msg00099.html https://llvm.org/bugs/show_bug.cgi?id=22662	2016-09-28 20:31:04 +03:00
Vladimir Serbinenko	323ef2bdc3	asm-tests/i386-pc: Check that near jumps are 2 bytes. ... We already check that jump over 300 bytes gap is 3 bytes in code16-mode. Some clang versions generate 3-byte opcode for short jumps which makes boot.img blow over 512-byte limit. Enforce -no-integrated-as in such cases	2015-11-11 18:14:25 +00:00
Vladimir Serbinenko	f16b8c0405	Relax requirements on asm for non-BIOS i386 platforms. ... These platforms don't have a hard limit on size of resulting code16 code, so we don't care if assembly is bigger than necessarry.	2015-02-21 20:18:18 +01:00
