- Subject: Lost patch - multiple entry points for x86 PIC
I was investigating what it would take to make the back end support
multiple entry points, which could be useful to several language front
ends. I discovered that it already does support them, more or less;
core support was added by Catherine Moore in 1999, and Jan fixed some
bugs in 2001. There's currently no way to make them be external or
weak symbols, but that's a detail.
The support is currently not used for anything whatsoever. Jan posted
a patch in February 2001 which caused the x86 back end to use it to
optimize intra-module calls in PIC mode, but that patch was never
reviewed. It's at http://gcc.gnu.org/ml/gcc-patches/2001-02/msg01373.html.
Anyone know why this one got lost?
