Log:
PR debug/83917
* configure.ac (AS_HIDDEN_DIRECTIVE): AC_DEFINE_UNQUOTED this to
$asm_hidden_op if visibility ("hidden") attribute works.
(HAVE_AS_CFI_SECTIONS): New AC_DEFINE.
* config/i386/i386-asm.h: Don't include auto-host.h.
(PACKAGE_VERSION, PACKAGE_NAME, PACKAGE_STRING, PACKAGE_TARNAME,
PACKAGE_URL): Don't undefine.
(USE_GAS_CFI_DIRECTIVES): Don't use nor define this macro, instead
guard cfi_startproc only on ifdef __GCC_HAVE_DWARF2_CFI_ASM.
(FN_HIDDEN): Change guard from #ifdef HAVE_GAS_HIDDEN to
#ifdef AS_HIDDEN_DIRECTIVE, use AS_HIDDEN_DIRECTIVE macro in the
definition instead of hardcoded .hidden.
* config/i386/cygwin.S: Include i386-asm.h first before .cfi_sections
directive. Use #ifdef HAVE_AS_CFI_SECTIONS rather than
#ifdef HAVE_GAS_CFI_SECTIONS_DIRECTIVE to guard .cfi_sections.
(USE_GAS_CFI_DIRECTIVES): Don't define.
* configure: Regenerated.
* config.in: Likewise.
