ia32 implies 32bit, while these files provide descriptions for IA32, X86_64, and X32 architectures. The term "x86" fits this used better without resorting to using the term "Intel" which isn't quite right as it excludes things like the tune-c3 file describing a Via CPU.

- 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'.
