- Initial version
Most of the items for the X86 architectures are defined in the single arch-x86 file.
Three ABIs are define, m32, mx32 and m64.
The following is the list of X86 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'.
