levels: -- none: no lax vector conversions [new GCC default] -- integer: only conversions between integer vectors [old GCC default] -- all: all conversions between same-size vectors [Clang default] For now, Clang still defaults to "all" mode, but per my proposal on cfe-dev (2019-04-10) the default will be changed to "integer" as soon as that doesn't break lots of testcases. (Eventually I'd like to change the default to "none" to match GCC and general sanity.) Following GCC's behavior, the driver flag -flax-vector-conversions is translated to -flax-vector-conversions=integer. This reinstates r371805, reverted in r371813, with an additional fix for lldb. llvm-svn: 371817
