Hello All,
I am busy merging the GCC trunk branch (i.e. future GCC 6) into the MELT
branch & plugin.
I am noticing a strange thing.
I was able to merge GCC trunk svn rev. 227945 into the MELT branch (svn
rev. 233352) without any issues.
Now, I am trying to merge into the MELT branch
svn merge -r227926:227945 ^/trunk
Notice that the merge above is quite small, and AFAIU did not touch any
gengtype related stuff.
But strangely, the merged build is failing in gengtype:
build/gengtype -v \
-r gtype.state
gengtype reading state file gtype.state;gengtype read 1085612 bytes.

Here are lines 252-267 of my gcc/melt/generated/meltrunsup.h
/*gtyctypebox gtyctyp #4 CTYPE_GIMPLE*/
struct GTY (()) meltgimple_st /* when MELTOBMAG_GIMPLE*/
{
meltobject_ptr_t discr;
gimple val;
operator melt_ptr_t ()
{
return reinterpret_cast<melt_ptr_t>(this);
}
}; /* end of meltgimple_st */
struct GTY (()) entrygimplemelt_st /* for MELTOBMAG_MAPGIMPLES*/
{
gimple e_at;
melt_ptr_t e_va;
};
FWIW, the gcc/melt/generated/meltrunsup.h file did not change in the
MELT branch since long time ago.
Do you have any clues about what has changed in gengtype about these tag
options in GCC 6? Or about the gimple type?
Regards.
PS. Of course the bug is very probably in the MELT branch, but it has
been a long time since I dived into gengtype. I can't figure out the error.
