4 | Most of the items for the X86 architectures are defined in the single | ||
5 | arch-x86 file. | ||
6 | |||
7 | Three ABIs are define, m32, mx32 and m64. | ||
8 | |||
9 | The following is the list of X86 specific variables: | ||
10 | |||
11 | X86ARCH32 - This is the 32-bit architecture GNU canonical arch, TUNE_ARCH. | ||
12 | |||
13 | X86ARCH64 - This is the 64-bit architecture GNU canonical arch, TUNE_ARCH. | ||
14 | |||
15 | The TUNE_PKGARCH is defined as follows: | ||
16 | |||
17 | TUNE_PKGARCH = ${TUNE_PKGARCH_tune-${DEFAULTTUNE}} | ||
18 | |||
19 | The package architecture for 32-bit targets is historical and generally | ||
20 | set to to match the core compatible processor type, i.e. i386. | ||
21 | |||
22 | For 64-bit architectures, the architecture is expected to end in '_64'. | ||
23 | |||
24 | If the x32 ABI is used, then the _64 is further extended with a '_x32'. | ||
