/*
* The addition of BROKEN_SIZE_32 (see template.h) and
* immediate_values[3] is a hacky workaround for Mac OS X's ld which
* doesn't recognize 0x80000000 (-2147483648) as a legitimate 32-bit
* relocatable offset. This prevents calls and jumps from being
* properly analyzed.
*
* For now we sacrifice the analysis of that bit pattern in the few
* template entries that would normally have it. We currently do this
* unconditionally because nobody has yet written a configure macro to
* detect this problem and then only use "BROKEN_SIZE_32" when we have
* a broken ld.
