The patch below simply removes this transformation. In order to get some idea of the performance impact, I compared the before-and-after -O2 assembly output of gcc.c-torture and gcc.dg for three targets:
i686-pc-linux-gnu powerpc-eabisim mips64-elf
In all three cases, only the output for the new testcase changed. There were no differences in the code generated for the other tests.
Bootstrapped & regression tested on i686-pc-linux-gnu. OK for mainline?
