[Buildroot] [PATCH v2 00/12] Fix GCC BUG 85180 per-package

[Buildroot] [PATCH v2 00/12] Fix GCC BUG 85180 per-package

[Giulio Benetti]

This patchset aims to build packages when building with Gcc affected by
Bug 85180 instead of not bulding them at all.
Bug 85180:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85180
is present in Gcc version < 8.x
The basic solution is to force compiling without optimization, so forcing
-O0 appending it to CFLAGS or CXXFLAGS according to programming language
used in package.

Giulio Benetti (12):
  toolchain: specify GCC_BUG_85180 is true only if GCC version < 8.x
  package/atop: fix BUG_85180 build timeout
  package/chocolate-doom: fix BUG_85180 build timeout

[Buildroot] [PATCH v2 01/12] toolchain: specify GCC_BUG_85180 is true only if GCC version < 8.x

[Giulio Benetti]

Bug 85180:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85180
has been fixed on Gcc version >= 8.x

So:
- add 'depends on !BR2_TOOLCHAIN_GCC_AT_LEAST_8' to 'config
  BR2_TOOLCHAIN_HAS_GCC_BUG_85180'.

[Giulio Benetti]

With Microblaze Gcc version < 8.x build hangs on compiling last files

-O0.

If BR2_TOOLCHAIN_HAS_GCC_BUG_85180=y force using -O0 passing it to

I have applied to master after reworking the commit title and commit
log, and also adjusting the code a bit (see below).

I believe:

ATOP_CFLAGS = $(TARGET_CFLAGS)

ifeq ($(BR2_TOOLCHAIN_HAS_GCC_BUG_85180),y)
ATOP_CFLAGS += -O0
endif

is more correct, otherwise you pass an empty CFLAGS when
BR2_TOOLCHAIN_HAS_GCC_BUG_85180 is false.

The second line is typically indented with one more tab.

As I said, I've applied to master after fixing those issues.

Thanks!

Thank you for rewording. Need to improve commit logs in general...

Yes totally right. Then I need to modify other patches for 
$(generic-package) packages as well as their commit logs at this point.

Why does flare-engine need this, but not jasper, which is also a
CMake-based package ?

This package is another example why this approach to override CXXFLAGS
is not good. Indeed, after your commit, the package contained this:

ifeq ($(BR2_TOOLCHAIN_HAS_LIBATOMIC),y)
LIBCPPRESTSDK_CONF_OPTS += -DCMAKE_CXX_FLAGS="$(TARGET_CXXFLAGS) -latomic"
endif

ifeq ($(BR2_TOOLCHAIN_HAS_GCC_BUG_85180),y)
LIBCPPRESTSDK_CONF_OPTS += -DCMAKE_CXX_FLAGS="$(TARGET_CXXFLAGS) -O0"
endif

Guess what happens when BR2_TOOLCHAIN_HAS_LIBATOMIC=y *and*
BR2_TOOLCHAIN_HAS_GCC_BUG_85180=y ? You loose the -latomic flag. That's
why I really prefer that we define an intermediate <pkg>_CXXFLAGS
variable.

I fixed that up, improved the commit log and applied to master. Thanks!

Because in flare-engine CMakeLists.txt there is no fallback to -O0, so 
that was the only decent way to force CMake to generate Makefiles 
without optimizations. I don't like it very much but it was the only way 
I've found.

Thank you for reviewing and improving all commit logs!

Applied to master after tweaking the CFLAGS logic and improving the

Could you be more specific ? How does it work for jasper and
libcpprestsdk, which are also based on CMake ?

Hello Thomas,

Yes, the problem here is that even if there's the way to append 
something to CMAKE_CXX_FLAGS, then any other CMAKE_CXX_FLAGS_* will be 
appended, so if I set CMAKE_CXX_FLAGS to -O0, I will obtain "-O0 -O2 -g".

This is due to the fact that we fall into one of the cases of the next 
if-elseif statements(in CMakeLists.txt):
"
if(CMAKE_BUILD_TYPE STREQUAL "Release")
   set(CMAKE_CXX_FLAGS_RELEASE "-O2 -g0")
   if(MINGW)
     set(CMAKE_CXX_FLAGS_RELEASE "-Wl,-subsystem,windows 
${CMAKE_CXX_FLAGS_RELEASE}")
   endif()
elseif(CMAKE_BUILD_TYPE STREQUAL "RelWithDebInfo")
   set(CMAKE_CXX_FLAGS_RELWITHDEBINFO "-O2 -g")
elseif(CMAKE_BUILD_TYPE STREQUAL "MinSizeRel")
   set(CMAKE_CXX_FLAGS_MINSIZEREL "-Os -g0")
elseif(CMAKE_BUILD_TYPE STREQUAL "Debug")
   set(CMAKE_CXX_FLAGS_DEBUG "-O0 -g3 -pg")
   set(CMAKE_EXE_LINKER_FLAGS_DEBUG "-pg")
   set(CMAKE_SHARED_LINKER_FLAGS_DEBUG "-pg")
   set(CMAKE_MODULE_LINKER_FLAGS_DEBUG "-pg")
endif()
"
where Release is the default and if BR2_ENABLE_DEBUG=y 
CMAKE_BUILD_TYPE=RelWithDebInfo according to flare-engine.mk
So I thought to set CMAKE_BUILD_TYPE to "Dummy" to jump over that 
if-elseif. But just right now I've realized that's enough to give 
-DCMAKE_BUILD_TYPE=
Empty is enough to jump over if-elseif.
Another way would be to patch CMakeLists.txt adding a fallback "else" to 
those if-elseif

What do you think?

Best regards

 Note that you could also get away without overriding CMAKE_BUILD_TYPE, and just
setting CMAKE_CXX_FLAGS_RELEASE. Definitions passed on the command line will
override the ones in CMakeFiles.txt (at least, I think so...).

 However, since we now still set CMAKE_BUILD_TYPE based on BR2_ENABLE_DEBUG,
that won't work :-(

 Another interesting example to consider how we should handle the
CMAKE_BUILD_TYPE...

 We could just always set CMAKE_BUILD_TYPE to Dummy or empty or whatever.
However, I'm not sure if that's the right thing to do. For other package infras,
we pass the optimisation options in CFLAGS, which still gives packages the
opportunity to change or override them. Looking at a few autotools packages,
they seem to generally append stuff to CFLAGS, but not really override it - and
autoconf itself takes care of not overriding user-passed CFLAGS. CMake packages,
on the other hand, seem to mess a lot more with optimisation flags (like the
example above). Also, I have the impression that CMake packages tend to also
override CMAKE_C_FLAGS (rather than append to it or override CMAKE_C_FLAGS_RELEASE).

 My feeling *at this time* is that the best option would be to set:

CMAKE_BUILD_TYPE=Buildroot
CMAKE_C_FLAGS_BUILDROOT=@TARGET_CFLAGS@

and not set CMAKE_C_FLAGS at all. For packages that do something sensible and
necessary under a BUILD_TYPE == Release condition, we can still do
package-specific override of BUILD_TYPE. And for packages that need something
extra, we can pass -DCMAKE_C_FLAGS_BUILDROOT="$(TARGET_CFLAGS) -O0"

 But it's very hard to be sure what is the best way, and what will cause the
least amount of breakage... So, to have the least amount of breakage, it would
be better to stick to CMAKE_BUILD_TYPE=Release and live with the fact that many
packages will override the optimisation flags...

 Bwerk, difficult to decide...

 Let's add Yann to the already huge Cc list :-)

 Arnout

 Because of this (and because we can't wait for CMake refactoring), I've
improved the comment in the .mk file a little and also rewrote the commit log
based on what Thomas wrote for the other commits, and applied to master, thanks.

 Arnout
