We perform a basic cleanup of the IA32 architecture and related tunings in order to match the rules and descriptions within the new tuning README file. A number of small issues were corrected in the "c3" tuning to bring it inline with the README.

- Initial version
|
|
|
|
Most of the items for the IA architecture are defined in the single
|
|
arch-ia32 file.
|
|
|
|
Three ABIs are define, m32, mx32 and m64.
|
|
|
|
The following is the list of ia32 specific variables:
|
|
|
|
X86ARCH32 - This is the 32-bit architecture GNU canonical arch, TUNE_ARCH.
|
|
|
|
X86ARCH64 - This is the 64-bit architecture GNU canonical arch, TUNE_ARCH.
|
|
|
|
The TUNE_PKGARCH is defined as follows:
|
|
|
|
TUNE_PKGARCH = ${TUNE_PKGARCH_tune-${DEFAULTTUNE}}
|
|
|
|
The package architecture for 32-bit targets is historical and generally
|
|
set to to match the core compatible processor type, i.e. i386.
|
|
|
|
For 64-bit architectures, the architecture is expected to end in '_64'.
|
|
|
|
If the x32 ABI is used, then the _64 is further extended with a '_x32'.
