Shared abi names are bad idea. For example |
| 41 |
mips abis : |
| 42 |
o32 |
| 43 |
n32 |
| 44 |
n64 |
| 45 |
eabi |
| 46 |
x86: |
| 47 |
x86_32 |
| 48 |
x86_x32 |
| 49 |
x86_64 |
| 50 |
|
| 51 |
Actualy first three one are equivalent in their internal behavior. But i dont |
| 52 |
think that its good idea to have one name for all. Think about multiarch |
| 53 |
installs where you can have binaries from different architectures in one |
| 54 |
system. |
