[CC'ed David, since the new compiler seems to cause the problems]
Sorry for the update bombing, but I found that the file where the
tzname symbol is being defined in triggers this error mesage in a
`make world`:
cc -fpic -DPIC -O -pipe -DLIBC_RCS -DSYSLIBC_RCS -I/usr/src/lib/libc/include -D__DBINTERFACE_PRIVATE -DINET6 -DPOSIX_MISTAKE -I/usr/src/lib/libc/../libc/locale -DBROKEN_DES -DYP -I/usr/obj/usr/src/i386/usr/include -c /usr/src/lib/libc/../libc/stdtime/localtime.c -o localtime.So
{standard input}: Assembler messages:
{standard input}:87: Warning: warning: unrecognized characters
`@GOTOFF' in expression
{standard input}:114: Warning: warning: unrecognized characters
`@GOTOFF' in expression
The assembler code looks like this (not that it is surrounding the
symbol we have problems with):
.L18:
leal (%edi,%edi,4),%edx
leal 1868+lclmem@GOTOFF(%ebx),%eax <<< [1]
leal (%eax,%edx,4),%edx
movl tzname@GOT(%ebx),%esi
movl 4(%edx),%ecx
sall $2,%ecx
movl %ebx,%eax
addl 8(%edx),%eax
addl $6988+lclmem@GOTOFF,%eax <<< [2]
movl %eax,(%ecx,%esi)
incl %edi
movl -4(%ebp),%eax
cmpl 8(%eax),%edi
jl .L18
Note that 'as' complains about [2], [1] is fine.
I'm not that familar with gas syntax, but it seems to be that this is
a syntax error generated by the new gcc, that @GOTOFF must be passed
one argument.
/usr/src/contrib/gcc/config/i386/i386.c:2988 seems to be the line that
writes the GOTOFF without an argument.
