First, let's not focus too much on that specific test.  There's others:

Tests that now fail, but worked before (20 tests):

rx-sim: gcc.c-torture/execute/ieee/hugeval.c execution,  -O1 
rx-sim: gcc.c-torture/execute/ieee/hugeval.c execution,  -O2 
rx-sim: gcc.c-torture/execute/ieee/hugeval.c execution,  -O2 -flto
-fno-use-linker-plugin -flto-partition=none 
rx-sim: gcc.c-torture/execute/ieee/hugeval.c execution,  -O2 -flto
-fuse-linker-plugin -fno-fat-lto-objects 
rx-sim: gcc.c-torture/execute/ieee/hugeval.c execution,  -O3 -g 
rx-sim: gcc.c-torture/execute/ieee/hugeval.c execution,  -Os 
rx-sim: gcc.c-torture/execute/ieee/inf-2.c execution,  -O1 
rx-sim: gcc.c-torture/execute/ieee/inf-2.c execution,  -O2 
rx-sim: gcc.c-torture/execute/ieee/inf-2.c execution,  -O2 -flto
-fno-use-linker-plugin -flto-partition=none 
rx-sim: gcc.c-torture/execute/ieee/inf-2.c execution,  -O2 -flto

rx-sim: gcc.c-torture/execute/ieee/inf-2.c execution,  -O3 -g 
rx-sim: gcc.c-torture/execute/ieee/inf-2.c execution,  -Og -g 
rx-sim: gcc.c-torture/execute/ieee/inf-2.c execution,  -Os 
rx-sim: gcc.c-torture/execute/ieee/inf-3.c execution,  -O1 
rx-sim: gcc.c-torture/execute/ieee/inf-3.c execution,  -O2 
rx-sim: gcc.c-torture/execute/ieee/inf-3.c execution,  -O2 -flto
-fno-use-linker-plugin -flto-partition=none 
rx-sim: gcc.c-torture/execute/ieee/inf-3.c execution,  -O2 -flto
-fuse-linker-plugin -fno-fat-lto-objects 
rx-sim: gcc.c-torture/execute/ieee/inf-3.c execution,  -O3 -g 
rx-sim: gcc.c-torture/execute/ieee/inf-3.c execution,  -Og -g 
rx-sim: gcc.c-torture/execute/ieee/inf-3.c execution,  -Os 

Given the magic hackery going on inside the RX target files, I wonder if we
should skip the entire ieee suite for rx.
