Subject: [PATCH 29/46] Enable SPE & AltiVec generation on powepc*linux target
|
|
|
|
When is configured with --target=powerpc-linux, the resulting GCC will
|
|
not be able to generate code for SPE targets (e500v1/v2).
|
|
GCC configured with --target=powerpc-linuxspe will not be able to
|
|
generate AltiVec instructions (for e6500).
|
|
This patch modifies the configured file such that SPE or AltiVec code
|
|
can be generated when gcc is configured with --target=powerpc-linux.
|
|
The ABI and speciffic instructions can be selected through the
|
|
"-mabi=spe or -mabi=altivec" and the "-mspe or -maltivec" parameters.
|
|
|
|
Upstream-Status: Inappropriate [configuration]
