Tried to build sys-devel/llvm-11.1.0 — failed too.
With disabled `abi_x86_32`, it compiles normally.
llvm-10.0.1 fails too
*** Bug 801421 has been marked as a duplicate of this bug. ***
From the other bug, this may be related to the kernel's CONFIG_COMPAT_32BIT_TIME being unset and kernel 5.13.x (haven't tried).
@toolchain, is there some active effort to switch to 64-bit time_t on x86? I don't see anything like that in glibc (i.e. it seems to always force the 32-bit type on 32-bit x86), so this looks like PEBKAC.
https://sourceware.org/glibc/wiki/Y2038ProofnessDesign is an effort and API design description. Similar to _FILE_OFFSET_BITS=64 it's an explicit option that would need to be enabled (at least while we are yet far away from 2038). For time_t it will be a _TIME_BITS=64. glibc-2.34 (not released yet) will provide it. The caveat is that even 32-bit time_t calls will use (and probably already uses partially) 64-bit kernel's time_t. Thus it's not a 1-to-1 mapping of 32-bit userspace time_t <=> CONFIG_COMPAT_32BIT_TIME and eventually need for CONFIG_COMPAT_32BIT_TIME should go away for 32-bit time_t. But that day is not today.
Ok, so the issue is not LLVM-specific. You can't disable CONFIG_COMPAT_32BIT_TIME if you want to use 32-bit applications on multilib amd64. I suppose we could add a config check somewhere (in glibc maybe?) but LLVM is not the place for it.
