Hi, Everyone
As x32 psABI (https://sites.google.com/site/x32abi/) is invented, do we need
a new triplet for system relies on triplet to figure out it's targeted on
x32 environment. The new triplet would look like
'x86_64-unknown-linux-gnux32' for x32 vs 'x86_64-unknown-linux-gnu' for
regular 64-bit. This's similar to EABI added to ARM or PowerPC, where
'arm-unknown-linux-gnueabi' vs. 'arm-unknown-linux-gnu'.
The new triple doesn't introduce a new target (still x86_64) but just a new
environment 'gnux32' to specify x32 ABI is used for code generation.
The current scheme documented on website (
https://sites.google.com/site/x32abi/) uses the existing triplet but specify
x32 ABI through compiler/linker options. It works for most compilers aware
of that, but how other tools not handling compiler/linker options knows the
current build is targeted on a different environment?
Any comments or alternative suggestion?
Yours
