Mainline bootstrap failure on Solaris 8/Intel

[Rainer Orth]

Mainline just started to fail bootstrap on Solaris 8/Intel: configured for
i386-pc-solaris2.8, the bootstrap stops at

./xgcc -B./ -B/vol/gcc/share/i386-pc-solaris2.8/bin/ -isystem /vol/gcc/share/i386-pc-solaris2.8/include -isystem /vol/gcc/share/i386-pc-solaris2.8/sys-include -O2 -DIN_GCC    -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -isystem ./include  -I. -I. -I/vol/gnu/src/gcc/gcc-dist/gcc -I/vol/gnu/src/gcc/gcc-dist/gcc/. -I/vol/gnu/src/gcc/gcc-dist/gcc/config -I/vol/gnu/src/gcc/gcc-dist/gcc/../include  -g0 -finhibit-size-directive -fno-inline-functions -fno-exceptions -fno-zero-initialized-in-bss -fPIC \
   -c /vol/gnu/src/gcc/gcc-dist/gcc/crtstuff.c -DCRT_BEGIN \
  -o crtbegin.o
Assembler: crtstuff.c
	"/var/tmp//ccDGzL0J.s", line 45 : Syntax error
	"/var/tmp//ccDGzL0J.s", line 96 : Syntax error

The offending lines are

	addl	$_GLOBAL_OFFSET_TABLE_+[.-$.L11], %ebx

and

	addl	$_GLOBAL_OFFSET_TABLE_+[.-$.L17], %ebx

The $ prefixes of the local labels are the culprit; removing them allows
the file to assemble.  crtstuff.[is] are included below for reference, but
i386.c (output_set_got) seems to be the culprit: compiling with -march=i686
(which sets TARGET_DEEP_BRANCH_PREDICTION) removes the failure:

  if (!flag_pic || TARGET_DEEP_BRANCH_PREDICTION)
    output_asm_insn ("add{l}\t{%1, %0|%0, %1}", xops);
  else
    output_asm_insn ("add{l}\t{%1+[.-%X2], %0|%0, %a1+(.-%X2)}", xops);
