Greetings. While regression-testing tcc against linux-2.4.37.11 kernel compilation another problem got introduced some time on tcc mob branch:
$ i386-tcc -E -P -I../linux/include setup.S \ -D__ASSEMBLY__ -D__KERNEL__ -D__BIG_KERNEL__ -o setup.s ### inside a comment section number parsing isn't ignored although it should be: # Ye Olde Traditional Methode. Returns the memory size (up to 16mb or # 64mb, depending on the bios) in ax. ### <- line 391 mem88: ### yields -> setup.S:391: error: invalid number Although tcc doesn't support 16bit real-mode assembly, it was possible before to pre-process the mentioned assembly file with it and then dumping the pre-processed output into binutils-as. The assembly parsing problem got introduced some time in between commit e7262accb6e6965452e7f82c0ff281ef8412af4d (march 2023,assembly parsing OK) ... latest HEAD (2024, problem with assembly/pre-processing parsing FAILURE) I could not in detail identify/bisect exactly which commit introduced the problem, nor haven't i got a patch to offer for it yet. Let me know if further details are necessary to re-produce the issue. Currently i'm idling in #tcc channel at OFTC. Regards. aggi --
