Optimized tunings must NOT +change the definiton of TUNE_PKGARCH. TUNE_PKGACH_tune- will be +ignored. The format of the package arch is enforced by the TUNE_PKGARCH +default. The format must be of the form: +[t][e][hf][b][-vfp][-neon] + +TUNE_PKGARCH is defined as: +${ARMPKGARCH}${ARMPKGSFX_THUMB}${ARMPKGSFX_DSP}${ARMPKGSFX_EABI}${ARMPKGSFX_ENDIAN}${ARMPKGSFX_FPU} + +ARMPKGARCH - This is the core package arch component specified by each +tuning. This is the primary identifier of a tuning. Usual values are: +arm, armv4, armv5, armv6, armv7a, etc. + +ARMPKGSFX_THUMB - This is the thumb specific suffix. Curently it is +defined in feature-arm-thumb.inc. + +ARMPKGSFX_DSP - This is the DSP specific suffix. Currently this is set +to 'e' when on armv5 and the dsp feature is enabled. + +ARMPKGSFX_EABI - This is the eabi specific suffix. There are currently +two defined ABIs specificed, standard EABI and Hard Float (VFP) EABI. +When the callconvention-hard is enabled, "hf" is specified, otherwise it +is blank. + +ARMPKGSFX_ENDIAN - This is the endian specific suffix. It is defined in +the core arch-arm.inc file. + +ARMPKGSFX_FPU - This is the FPU specific suffix. The suffix indicates +specific FPU optimizations. 'vfp' and 'neon' are both defined. -- cgit v1.2.3-54-g00ecf
