Description

ia32 build does not set -march for user space. This means, for example, that even if we set CPU to 486, user-space code does not run properly on 486 processor (qemu-system-i386 -M isapc).

Before switch to meson here's what we did:

ifeq ($(PROCESSOR),i486)
        COMMON_CFLAGS += -march=i486
else
        COMMON_CFLAGS += -march=pentium
endif

so there was just special case for 486. Probably because of the bug where if we set -march=pentium4, then tester malloc1 and tester malloc3 tend to fail.

Resolution: → fixed
Status: new → closed

With #832 and #833 fixed, we can now enable march for ia32 user-space.

Fixed in changeset ​7eec25fcc916d12889b4ae19ba7f3e78678be3dd.
