Subject: [RISCV] Update computeTargetABI from llc as well as clang
X-Git-Tag: upstream/15.0.7~15322
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4e115b7d881136947c083e12f62010bc6b1d3f00;p=platform%2Fupstream%2Fllvm.git

[RISCV] Update computeTargetABI from llc as well as clang

Clang computes the default ABI if -mabi is empty
and encode it in LLVM IR module flag since D105555.
For correctness, llc need to give the same target-abi
(Options.MCOptions.ABIName) with ABI encoded in IR.
The getSubtargetImpl already has a check for them only if
Options.MCOptions.ABIName is not empty.

In order to get more robustness we could have a check for
explicit ABI, but now we have two different logic to
compute the default ABI.

The front-end ABI is defautl to the ilp32/ilp32e/lp64, and
ilp32d/lp64d when hardware support for extension D.
The backend ABI is default to the ilp32/ilp32e/lp64.
