Subject: [NFC][Clang] Modify expect of fail test or XFAIL because CSKY align is different
X-Git-Tag: upstream/15.0.7~7435
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dca37af061fbe6590399dfb4e3fd3dda16d63144;p=platform%2Fupstream%2Fllvm.git

[NFC][Clang] Modify expect of fail test or XFAIL because CSKY align is different

CSKY is always in 4-byte align, no matter it's long long type.
For global aggregate variable, it's 4-byte align if its size is bigger than or equal to 4 bytes.
