Sadly the latest optimization broke completely everything. The asm code isn't gas compliant. the libFLAC linker script has a typo, disabling the asm optimization and/or altivec won't let a correct build anyway. Instant fixes for the asm stuff: sed -i -e"s:;:\#:" on the lpc_asm.s to load address instead of addis+ori you could use lis and la and PLEASE use the @l(register)

I've been working on adding support for a (semi-proprietary) extension for PowerPC called "Paired-Singles". It's a SIMD instruction set supporting various operations on a vector of 2 32-bit floating point numbers. The Extension is found in the PowerPC 750CL, modified variants of it are used in the Nintendo GameCube (Gekko), the Nintendo Wii (Broadway) and the Nintendo Wii U
