[Bug rtl-optimization/20413] New: VOIDmode LABEL_REFs are generated

[amylaar at gcc dot gnu dot org]

Various parts of the compiler generate LABEL_REFS with VOIDmode instead of Pmode.
This can cause some optimizations to be missed because two pieces of code
might be identical, except for the mode of their LABEL_REFS - then they still
compare as non-equal, e.g. for if-conversion or cross-jumping.

For targets that have varying Pmode settings and therefore use jump patterns
that don't specify the mode so that they can match e.g. either SImode of DImode,
the situation is more dire: when reload has to load the label into a register,
it needs the mode of the label_ref to determine the load of the reload.
VOIDmode in this place leads to an ICE, which is likely to prevent building
the gcc support libraries.

I have removed the build keyword because I have found an ugly hack -
wildcard splitters - that allow the sh64-elf build to proceed
despite of this bug.

Note this workaround doesn't work when swing modulo scheduling is enabled,
because the latter generates more invalid LABEL_REFS after the pre-reload
splitting pass.  Hence gcc.dg/20050321-1.c doesn't work, and if swing
modulo scheduling becomes the default before this bug is fixed, sh64-elf
will fail to build.

[Bug rtl-optimization/20413] VOIDmode LABEL_REFs are generated

[giovannibajo at libero dot it]

------- Additional Comments From giovannibajo at libero dot it  2005-04-11 12:48 -------
I have a very naive question: if LABEL_REFS should always be generated with 
Pmode, can't we add an assert if gen_rtx_LABEL_REF is called with a different 
mode? Or better, remove the mode argument altogether?

Well, striclty speaking, there are some special cases where LABEL_REF is 
generated in ptr_mode.
