[Buildroot] [PATCH 00/31] Removal of BR2_GCC_TARGET_TUNE and other arch/ updates

[Buildroot] [PATCH 00/31] Removal of BR2_GCC_TARGET_TUNE and other arch/ updates

[Thomas Petazzoni]

Hello,

As discussed during the Buildroot Developers meeting, this patch
series implement a few changes to the handling of the
BR2_GCC_TARGET_{ARCH,CPU,TUNE} options.

In sequence, this patch series:

 - PATCH 1 and 2 fix some dangling architecture dependency and a typo
   on a NIOS 2 architecture dependency. They are really fixes for
   existing issues.

 - PATCH 3 introduces a number of ARM architecture blind options:
   BR2_ARM_CPU_ARMV4, BR2_ARM_CPU_ARMV4T, ...,
   BR2_ARM_CPU_ARMV7A. These options will allow to simplify testing
   against an ARM architecture (instead of using each individual ARM
   core), and also allow to remove tests against BR2_GCC_TARGET_ARCH
   on ARM, since we later get rid of all values for this variable on
   ARM as part of a later patch in this series.

 - PATCH 4 to 20 make use of those new blind options to replace a
   number of dependencies/conditions on individual ARM cores by
   dependencies/conditions on ARM architecture levels.

 - PATCH 21 fixes the dhcpcd package as it uses the
   BR2_GCC_TARGET_ARCH value, which may not always exists on certain
   architectures.

 - PATCH 22 and 23 remove the BR2_GCC_TARGET_ARCH values from the ARM
   architecture, since they are causing conflicts with the
   BR2_GCC_TARGET_CPU values. We now only specify the -mcpu value
   (through BR2_GCC_TARGET_CPU), and let gcc derive the corresponding
   ARM architecture. This fixes a long standing bug report where
   Buildroot would pass conflicting -march and -mcpu values for
   certain versions of gcc.

 - PATCH 24 prepares ffmpeg for the removal of BR2_GCC_TARGET_TUNE by
   using BR2_GCC_TARGET_ARCH or BR2_GCC_TARGET_CPU instead.

 - PATCH 25 to 28 modifies the architecture definitions to no longer
   use BR2_GCC_TARGET_TUNE, and instead use BR2_GCC_TARGET_CPU or
   BR2_GCC_TARGET_ARCH as appropriate.

 - PATCH 29 to 31 finally get rid of BR2_GCC_TARGET_TUNE entirely
   since it is no longer used.

[Buildroot] [PATCH 01/31] ffmpeg: remove dangling reference to BR2_arm10

[Thomas Petazzoni]

BR2_arm10 has been removed in commit
d60489a6e5e733a20d18b128646088981da57867 ("arch: remove BR2_arm10t"),
so there is no point in keeping a reference to it in the ffmpeg
package.

[Buildroot] [PATCH 03/31] arch/arm: add blind options to know the ARM architecture

[Thomas Petazzoni]

In preparation to the removal of BR2_GCC_TARGET_ARCH for ARM, this
commit introduces a number of blind options for each ARM architecture,
so that packages/toolchains that had dependencies using
BR2_GCC_TARGET_ARCH can continue to express their dependencies. It can
also be used to simplify package dependencies that were using the
individual ARM core options.

Instead of using the exhaustive list of Cortex-A ARM cores, use

which was true a long time ago, but was no longer true since it was

Refactor the toolchain-external Config.in file to use the
BR2_ARM_CPU_ARM*. All of the changes are purely mechanical, except for
the Arago ARMv5 toolchain: it had a 'depends on BR2_GCC_TARGET_ARCH !=
"armv5t"', but armv5t was not a possible value for
BR2_GCC_TARGET_ARCH. Since the toolchain is ARMv5TE, the only ARM
architectures we need to exclude are ARMv4 and ARMv4T.

[Buildroot] [PATCH 21/31] dhcpcd: do not pass --target option

[Thomas Petazzoni]

dhcpcd is using $(BR2_GCC_TARGET_ARCH) as the value of its --target
option. However, depending on the architecture, this value might be
empty.

After inspecting the dhcpcd configure script, it turns out that in
fact the --target option has the following semantic:

  --target=TARGET   configure for building compilers for TARGET [HOST]

So it is very much like the --target option of regular,
autoconf-based, configure scripts. Since dhcpcd is not a compiler,
passing --target is pointless. Moreover, as long as --os=linux is
passed, passing --host or --target is completely ignored by the
configure script.

[Buildroot] [PATCH 22/31] arch/arm: do not distinguish revisions of ARM1136JF-S

[Thomas Petazzoni]

In commit 88cf3bb91792c9c04586e14f293d89a6e0c13e1d
("arch/Config.in.arm: Use armv6k for arm1136jf-s rev1"), Beno?t
Th?baudeau added separate options for the revision 0 and revision 1 of
the ARM1136JF-S processor, so that different -march values could be
used (armv6j for revision 0, armv6k for revision 1).

However, this is preventing the removal of the BR2_GCC_TARGET_ARCH
option, which we need to do to give only the CPU type to gcc, and let
it decide the architecture variant that matches. This is because this
story of revision 0 vs. revision 1 is the only case where -mcpu
doesn't fully define the CPU.

Moreover, a quick test with gcc shows that -march=armv6j
-mcpu=arm1136jf-s is accepted, while -march=armv6k -mcpu=arm1136jf-s
makes gcc complain: " warning: switch -mcpu=arm1136jf-s conflicts with
-march=armv6k switch".

In addition, gcc 5 will apparently no longer allow to pass all of
--with-arch, --with-cpu and --with-tune, so we will anyway have to
rely only on one of them.

As a consequence, this commit basically reverts
88cf3bb91792c9c04586e14f293d89a6e0c13e1d and provides only one option
for ARM1136JF-S. If the two revisions are really different, then they
should be supported in upstream gcc with different -mcpu values.

Note that the removal of the two options should not break existing
full .config, since the hidden option BR2_arm1136jf_s becomes again a
visible option to select the CPU.

[Buildroot] [PATCH 23/31] arch/arm: remove BR2_GCC_TARGET_ARCH definitions on ARM

[Thomas Petazzoni]

On ARM, we were defining both the CPU type and the architecture
variant. However, depending on the version of gcc, a given combination
of (CPU, architecture) may not be the same. Since the architecture
variant is implied by the CPU type, given the former is not necessary,
and we can simply specify the latter.

From the gcc documentation:

  This specifies the name of the target ARM processor. GCC uses this
  name to derive the name of the target ARM architecture (as if
  specified by -march) and the ARM processor type for which to tune
  for performance (as if specified by -mtune). Where this option is
  used in conjunction with -march or -mtune, those options take
  precedence over the appropriate part of this option.

Note that we verified that for all BR2_GCC_TARGET_ARCH value that
existed, a proper BR2_GCC_TARGET_CPU value is defined.

[Buildroot] [PATCH 24/31] ffmpeg: use arch and cpu instead of tune

[Thomas Petazzoni]

ffmpeg currently uses BR2_GCC_TARGET_TUNE as the --cpu option
value. However, there are multiple architectures for which
BR2_GCC_TARGET_TUNE is not used. After inspecting the ffmpeg configure
script, we concluded that using the BR2_GCC_TARGET_CPU value if
available, or the BR2_GCC_TARGET_ARCH value as a fallback was the
appropriate behavior.

This allows to remove the reference to BR2_GCC_TARGET_TUNE, which is
one step towards the removal of this option.

[Buildroot] [PATCH 25/31] arch/x86: get rid of BR2_GCC_TARGET_TUNE

[Thomas Petazzoni]

According to the gcc documentation, -march implies -mtune on x86, so
defining both BR2_GCC_TARGET_ARCH and BR2_GCC_TARGET_TUNE is
redundant. Therefore, this commit removes the definition of
BR2_GCC_TARGET_TUNE on x86.

However, while doing so, it adds one new case for BR2_GCC_TARGET_ARCH:
using -march=generic when BR2_x86_generic is selected.

[Buildroot] [PATCH 26/31] arch/sparc: get rid of BR2_GCC_TARGET_TUNE

[Thomas Petazzoni]

On SPARC, BR2_GCC_TARGET_TUNE was only used for one specific case, the
BR2_sparc_v8. There is actually no reason to not use
BR2_GCC_TARGET_CPU instead for this, as all values supported for
-mtune are also supported for -mcpu. Therefore, the only
BR2_GCC_TARGET_TUNE case is moved as a BR2_GCC_TARGET_CPU case.

[Buildroot] [PATCH 27/31] arch/powerpc: get rid of BR2_GCC_TARGET_TUNE

[Thomas Petazzoni]

According to the gcc documentation for PowerPC options:

'-mtune=CPU_TYPE'
     Set the instruction scheduling parameters for machine type
     CPU_TYPE, but do not set the architecture type, register usage, or
     choice of mnemonics, as '-mcpu=CPU_TYPE' would.  The same values
     for CPU_TYPE are used for '-mtune' as for '-mcpu'.  If both are
     specified, the code generated will use the architecture, registers,
     and mnemonics set by '-mcpu', but the scheduling parameters set by
     '-mtune'.

In the case of Buildroot where we only target a specific system, using
-mtune therefore doesn't make much sense, and using -mcpu would be
more appropriate. As a consequence, this patch makes PowerPC use
BR2_GCC_TARGET_CPU instead of BR2_GCC_TARGET_TUNE.

Indirectly related to your patch: HAS_THUMB2 should select HAS_THUMB,
since Thumb-2 is a superset of Thumb.

Then, you could just have (for example) BR2_ARM_CPU_ARMV4 and ditch
BR2_ARM_CPU_ARMV4T since it can be reconstructed from BR2_ARM_CPU_ARMV4
&& HAS_THUMB.

The reasonning is that few package actually require knowing the exact
variant, but rather the instruction set generation. Thus knowing about
armv4t is equivalent to knowing about armv4 for most. Those few that
actuallt require the Thumb isns would need to use the HAS_THUMB option,
which very purpose is just that, telling whether thumb is supported or
not (or HAS_THUMB2 for Thumb-2).

As for the J version, I wonder if we need to introduce a HAS_JAZELLE
option. For armv6zk (Wikpedia refer to it as armv6kz), I also doubt we
need to introduce a HAS_TRUSTZONE option either. For armv7a, I think we
can just use armv7, since we will probably never support the R and M
profiles in Buildroot.

Yann E. MORIN.

[Buildroot] [PATCH 24/31] ffmpeg: use arch and cpu instead of tune

[Yann E. MORIN]

Thomas, All,

On 2014-10-19 22:07 +0200, Thomas Petazzoni spake thusly:
> ffmpeg currently uses BR2_GCC_TARGET_TUNE as the --cpu option
> value. However, there are multiple architectures for which
> BR2_GCC_TARGET_TUNE is not used. After inspecting the ffmpeg configure
> script, we concluded that using the BR2_GCC_TARGET_CPU value if
> available, or the BR2_GCC_TARGET_ARCH value as a fallback was the
> appropriate behavior.
> 
> This allows to remove the reference to BR2_GCC_TARGET_TUNE, which is
> one step towards the removal of this option.

 +1 to this. I made the same reasoning.

 I think there was something wrong in the original, because arm1176jz-s doesn't
have VFP.

 Also, there's a bunch of Cortex-A variants that were added after this selection
was merged and they all have VFP.

 With that in mind, probably BR2_ARM_CPU_HAS_VFPV2 is more appropriate.

 Arnout

Right.

Agreed with all of that.

But not with that one: I now have a Cortex-M platform, and I hope to do
something with it at some point. And since Cortex-M platforms don't
have a MMU, it's significant difference between ARMv7-A and ARMv7-M.

Best regards,

Thomas
