History

John Polstra 87f11ab41b Fix a bug that caused incorrect PIC code to be generated for exceptions.

The symptom was an assembler warning

    "GOT relocation burb: `___EXCEPTION_TABLE__' should be global"

followed (sometimes) by a core dump.  The fix makes the compiler
generate the correct GOTOFF addressing for that symbol, rather than the
GOT addressing it was emitting before.

Warning:  There is still at least one serious bug in the i386 exception
code for PIC.  The exception code that is generated clobbers the GOT
register (%ebx) and then tries to use it later.  That leads to core
dumps at program execution time.  I know where the problem is, but I do
not have a fix for it at this time.  Until it is fixed, exceptions will
not work in PIC code.  This is a general problem for all i386 platforms;
it is not specific to FreeBSD.
