Bug ID: 97314
Summary: bootstrap failure on i686-linux-gnu with
--enable-checking=yes,extra,rtl
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: doko at debian dot org
Target Milestone: ---
seen with the gcc-10 branch 20201003, while originally building that for
another architecture. The build succeeds on another 32bit arch
(arm-linux-gnueabihf) and on 64bit archs, but fails on i686-linux-gnu.
The build is also configured with --enable-default-pie and other hardening
options turned on by default, built with make -j2.

Yes, but for me it was resolved with
r11-3518-g37ffe56c01e4a9e80a3b3c4f5beb86d80a0663db. If the (huge) switch is
optimized by switchconv, then DF doesn't run into the latent problematic case.
I'm not using --enable-default-pie though.

I see the same thing for arm-linux-gnueabihf on trunk, also on
insn-extract.o. It's specific to RTL checking for me too.
I found it does work if I bootstrap with --enable-checking=yes,extra,
flip ENABLE_RTL_CHECKING to 1 in auto-host.h, and then recompile
insn-extract.c. But it does take a large amount of VM:
phase parsing : 51.10 ( 27%) 43.64 ( 74%) 94.74 ( 38%)
1334M ( 73%)
This used to work “a while ago” but I don't know when it stopped.
The file has 9975 lines, 435KiB, but that's a bairn compared to some
of the stuff we kick out. Perhaps it's just the sheer number of
(nested) XEXP macro expansions?

8441545d4f2afb9e9342e0dac378eafd03f00462 now builds insn-extract.o without rtl
checking unconditionally.
