https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99448

--- Comment #2 from Matthias Klose  ---
the compiler is configured with --enable-default-pie.

so this one sometimes fails with different reasons when retrying:

lto1: error: filter/andfiltertest.o: file too short
lto1: fatal error: errors during merging of translation units
compilation terminated.
lto-wrapper: fatal error: g++ returned 1 exit status
compilation terminated.
/usr/bin/ld: error: lto-wrapper failed
collect2: error: ld returned 1 exit status

and doesn't fail now when just retrying the link command manually now ...

these flags are passed to the upstream build system:

CFLAGS=-g -O2 -ffile-prefix-map=/packages/tmp/log4cxx-0.11.0=. -flto=auto
-ffat-lto-objects -fstack-protector-strong -Wformat -Werror=format-security

I'm able to reduce the amount of object files involved in this ICE. But then
trying to rebuild the package with -save-temps makes the ICE disappear.

--- Comment #1 from Matthias Klose  ---
 doko, odd, don't know how that happens, something must have missed
merging the sections together.
 doko, Since this is mips there might be some confusion about section
types/flags. I would look to see if those sections have different types/flags
and then try to work back who created which with those. e.g. both gas and gcc
can create a .debug_line_str section.

[Bug target/97323] [10/11 Regression] ICE 'verify_type' failed on arm-linux-gnueabihf

[doko at debian dot org via Gcc-bugs]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97323

--- Comment #4 from Matthias Klose  ---
this started with a regression hunt in-between with GCC 9 and GCC 10. However
the test case with a compiler configured with the extra and rtl checking
already produces this ICE with 2018-01-01 and 2019-01-01 builds.

target_cpu is powerpc64le

Makefile.rtl:

ifeq ($(strip $(filter-out powerpc64,$(target_cpu))),)
  ifneq ($(strip $(MULTISUBDIR)),/ppc)
LIBGNAT_TARGET_PAIRS += $(GNATRTL_128BIT_PAIRS)
EXTRA_GNATRTL_NONTASKING_OBJS += $(GNATRTL_128BIT_OBJS)

LIBGNAT_TARGET_PAIRS += $(GNATRTL_128BIT_PAIRS)
EXTRA_GNATRTL_NONTASKING_OBJS += $(GNATRTL_128BIT_OBJS)
  endif
endif
  endif

looks like this logic makes the assumption that any power architecture is
always mutilib'd, which is only true for powerpc-linux-gnu and
powerpc64-linux-gnu, but not powerpc64le-linux-gnu.

I didn't check where else this assumption is made.

seen building elkcode-6.3.2 on x86_74-linux-gnu
gcc-10 branch, compiler configured with -enable-checking=yes,extra,rtl, didn't
check the trunk yet.

I can reproduce this locally, replacing mpif90 with gfortran. I'm failing to
construct a test case outside the build directory.

[Bug other/98027] New: CET support is documented to be explicitly enabled, however it's enabled by default

[doko at debian dot org via Gcc-bugs]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98027

Bug ID: 98027
   Summary: CET support is documented to be explicitly enabled,
however it's enabled by default
   Product: gcc
   Version: 10.2.1
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: other
  Assignee: unassigned at gcc dot gnu.org
  Reporter: doko at debian dot org
  Target Milestone: ---

CET support is documented to be explicitly enabled, however it's enabled by
default.

install.texi reads:

@item --enable-cet
@itemx --disable-cet
Enable building target run-time libraries with control-flow
instrumentation, see @option{-fcf-protection} option.  When
@code{--enable-cet} is specified target libraries are configured
to add @option{-fcf-protection} and, if needed, other target
specific options to a set of building options.

The option is disabled by default.  When @code{--enable-cet=auto}
is used, it is enabled on Linux/x86 if target binutils
supports @code{Intel CET} instructions and disabled otherwise.
In this case the target libraries are configured to get additional
@option{-fcf-protection} option.

however it's still enabled when no --enable-/--disable-cet configure options is
given.

Please either update the documentation or the behavior. Seems to be the case
for the gcc-10 branch as well.

unreleated question: when do you configure with -fcf-protection -mshstk, and
when just with -fcf-protection?

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.

--- Comment #15 from Matthias Klose  ---
Jeff, this is a two-step build: First a build using the configure options in
comment #9, then a second build using the just built compiler for the jit build
with

CONFARGS_JIT := \
$(filter-out --enable-languages=% \
--enable-libstdcxx-debug %bootstrap,\
  $(CONFARGS)) \
--enable-languages=c++,jit \
--enable-host-shared \
--disable-bootstrap

So maybe you can work around that by doing a bootstrap build for the second
build, but that wouldn't solve the problem of having a miscompiled build from
the first build?
