Commit message shamelessly copied from 1777beb6b129 by jakub:
This function, because it is sometimes called even outside of function
bodies, uses create_tmp_var_raw rather than create_tmp_var. But in order
for that to work, when first referenced, the VAR_DECLs need to appear in a
TARGET_EXPR so that during gimplification the var gets the right
DECL_CONTEXT and is added to local decls.
Bootstrapped & regtested on mips64el-linux-gnu. Ok for trunk and backport
to 11, 10, and 9?
gcc/
* config/mips/mips.c (mips_atomic_assign_expand_fenv): Use
TARGET_EXPR instead of MODIFY_EXPR.
