This part is not good. With your change, the "fixes" on pixman and
liquid-dsp are now also applied when using the SPE-capable 2012.03
toolchain, while in the past they were only used for the non-SPE
capable 2010.xx and 2011.xx toolchains:
-# Altivec detection isn't reliable for CS toolchains
-ifeq ($(BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_POWERPC201103)$(BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_POWERPC201009),y)
-PIXMAN_CONF_OPTS += --disable-vmx
-endif
config BR2_PACKAGE_LIQUID_DSP
bool "liquid-dsp"
depends on BR2_TOOLCHAIN_USES_GLIBC || BR2_TOOLCHAIN_USES_MUSL
depends on !BR2_STATIC_LIBS
- # These result in internal compiler error
- depends on !BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_POWERPC201103
- depends on !BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_POWERPC201009
help
Liquid-DSP is a free and open-source signal processing
library for software-defined radios written in C. Its
So either we need to have two Config.in symbols:
BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_POWERPC and
BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_POWERPC_SPE, or you need to adjust
the fixes to test that SPE is not set, like:
-ifeq ($(BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_POWERPC):$(BR2_POWERPC_CPU_HAS_SPE),y:)
-PIXMAN_CONF_OPTS += --disable-vmx
-endif
Best regards,

I noticed that this toolchain depends on BR2_powerpc_SPE which allow to select BR2_powerpc_8548 (e500v2) but also BR2_powerpc_8540 (e500v1). Are you sure the system build for a PowerPC 8540 can work with this toolchain ? Do you think we can use BR2_powerpc_8548 instead of BR2_powerpc_SPE ? I would do something like: config BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_POWERPC_E500V2 bool "Sourcery CodeBench PowerPC 2012.03 (e500v2 only)" depends on BR2_powerpc depends on BR2_powerpc_8548 depends on BR2_HOSTARCH = "x86_64" || BR2_HOSTARCH = "x86" depends on !BR2_STATIC_LIBS select BR2_TOOLCHAIN_EXTERNAL_GLIBC select BR2_TOOLCHAIN_HAS_NATIVE_RPC select BR2_INSTALL_LIBSTDCPP select BR2_HOSTARCH_NEEDS_IA32_LIBS select BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_2 select BR2_TOOLCHAIN_GCC_AT_LEAST_4_6 help Sourcery CodeBench toolchain for the PowerPC architecture, from Mentor Graphics.

It has support for the following variants: - e500v2 glibc, SPE, 32 bits For the 2011.03 toolchain we keep Kconfig as it was previously: config BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_POWERPC bool "Sourcery CodeBench PowerPC 2011.03" depends on BR2_powerpc depends on BR2_HOSTARCH = "x86_64" || BR2_HOSTARCH = "x86" depends on !BR2_STATIC_LIBS select BR2_TOOLCHAIN_EXTERNAL_GLIBC select BR2_TOOLCHAIN_HAS_NATIVE_RPC select BR2_INSTALL_LIBSTDCPP select BR2_HOSTARCH_NEEDS_IA32_LIBS # kernel headers: 2.6.38 select BR2_TOOLCHAIN_GCC_AT_LEAST_4_5 help Sourcery CodeBench toolchain for the PowerPC architecture, from Mentor Graphics.

As reported by Yann E. MORIN [1], the latest CS PowerPC toolchain (2012.03) requires a PPC CPU with SPE, which is basically two variants, 8540 (e500v1) and 8548 (e500v2) in Buildroot. All other PPC CPU can't use that toolchain. In order to keep at least one CS toolchain for all other PPC CPU, revert the removal of CS PowerPC 2011.03 and add a dependency on !BR2_POWERPC_CPU_HAS_SPE. In the same time add a dependency on BR2_POWERPC_CPU_HAS_SPE for the CS PowerPC 2012.03. Thereby, we can use the same trick as for the Linaro toolchain and keep only one Kconfig symbol. Also re-add the old CS toolchain handling for pixman and liquid-dsp. [1] http://lists.busybox.net/pipermail/buildroot/2015-December/148308.html Reported-by: "Yann E. MORIN" <yann.morin.1998@free.fr> Signed-off-by: Romain Naour <romain.naour@gmail.com> Cc: Gustavo Zacarias <gustavo@zacarias.com.ar> --- Gustavo, in the previous patch I removed your fix [1] for the CS PowerPC 2011.03 and 2010.09 toolchains. Since BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_POWERPC can be ether CS PowerPC 2011.03 or CS PowerPC 2012.03, I reverted this change. Do you know if the Altivec detection is still not realiable with 2012.03 ?
