Hi all. In general i dislike the CS powerpc toolchains, they're finicky and outdated, so i tend to roll my own via ct-ng or internal. That being said and going back to Romain's original mail, you can't have SPE and altivec at the same time, they're mutually exclusive. That's because SPE is basically a FPU bolted into CPU GP registers: for v1 it just implements single precision, for v2 it implements double (by extending the GP registers to 64 bits). Altivec requires a "classic" FPU with dedicated registers. Getting that out of the way the altivec woes come from gcc changing the semantics for enabling them: in the old wild west that was -faltivec, the standard/modern way is -maltivec. The problem lies with Apple if i'm not wrong, since they ditched powerpc a while ago back then they used an old gcc, hence -faltivec, and in many cases the tested condition is based on that assumption (powerpc = apple). Care must be taken since the calling convention for the asm-optimized code might be OSX rather than linux as well, hence just switching the knob to the new/standard way may do no good. Now back to SPE, since ABI can't be maintained between e500v1 and v2 for obvious reasons it was kind of decided to drop hard float from glibc, hence newer (eglibc >= 2.18 IIRC) versions can't be built targetting an e500v? without softfloat, so basically it's a dead path anyway (except uclibc*, it still has the hard float implementation in place, and screw the ABI). Regards.

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. Keep CS PowerPC 2011.03 as latest available version and add a second Kconfig symbol for the CS PowerPC 2012.03 since it's verry specific to one CPU type (e500v2). Previously it was possible to select the CS 2012.03 with a powerpc 8540 (e500v1) CPU but the sysroot provided by the toolchain only support the 8548 (e500v2) variant. Allow to select CS 2012.03 only with BR2_powerpc_8548. Also re-add the previous CS toolchain handling for pixman and liquid-dsp.
