[PATCH v3 09/11] rules.mak: Add base-arch() rule |
|
Date: |

Add a rule to return the base architecture for a QEMU target.
The current list of TARGET_BASE_ARCH is:
$ git grep TARGET_BASE_ARCH configure
configure:7785:TARGET_BASE_ARCH=""
configure:7795: TARGET_BASE_ARCH=i386
configure:7813: TARGET_BASE_ARCH=arm
configure:7846: TARGET_BASE_ARCH=mips
configure:7854: TARGET_BASE_ARCH=mips
configure:7864: TARGET_BASE_ARCH=openrisc
configure:7871: TARGET_BASE_ARCH=ppc
configure:7879: TARGET_BASE_ARCH=ppc
configure:7887: TARGET_BASE_ARCH=ppc
configure:7894: TARGET_BASE_ARCH=riscv
configure:7900: TARGET_BASE_ARCH=riscv
configure:7920: TARGET_BASE_ARCH=sparc
configure:7925: TARGET_BASE_ARCH=sparc
