Hi, the display of LSS16 files from a DISPLAY file (as documented in http://www.syslinux.org/wiki/index.php/SYSLINUX#Display_graphic_from_filename:) seems heavily broken since syslinux has been converted from assembler to C.

From: Matt Fleming <matt.fleming at intel.com> Since we can't use __intcall() for EFI, and since we can now have the ELF module code resolve all our symbols at runtime, we should delete as many references to __intcall() as possible and just access the symbols directly. The most interesting patch is the support for weak symbols. We need to be able to reference derivative-specific

I'm trying to add support for inline assembly and I keep getting this error: <jal> "<inline asm>:1:2: error: invalid instruction" which is due to the fact that MatchInstructionImpl() returns Match_MnemonicFail.

The first or second memset() seems redundant since it's never used in between. If we can assume when oreg is NULL intcall() never touches ireg, then we don't need the third memset().

(I?m using syslinux-6.03-pre02) printf () or dprintf ()? You need to watch what functions are available at the time you want to print. For example, printf isn't available until ldlinux.c32 is

We recently have upgraded syslinux and have noticed that the boot logo code via boot.txt no longer works. I have a couple patches that get it close to working but I appear to be having trouble with color maps. Is there someone would want to help me finish figuring this out? Any interest in the patches I have to fix the rle decoder?
