Could the __PRO__ (or something similar) be part of the cpp predefines for this configuration so non-gcc assembly can do the right thing? I know that at least libgloss and RTEMS have hppa assembly. Of course, this all begs the bigger question... how many embedded hppa users are there really? :) > 2002-03-26 Vladimir Makarov > > * pa/t-pro (TARGET_LIBGCC2_CFLAGS): New macro. > > * pa/lib2funcs.asm: Don't use .SPACE and .SUBSPACE if __PRO__ is > defined. > > Index: pa/lib2funcs.asm > =================================================================== > RCS file: /cvs/gcc/gcc/gcc/config/pa/lib2funcs.asm,v > retrieving revision 1.6 > diff -c -p -r1.6 lib2funcs.asm > *** lib2funcs.asm 2001/04/16 18:30:45 1.6 > --- lib2funcs.asm 2002/03/26 16:57:10 > *************** > *** 28,33 **** > --- 28,34 ---- > ; the Free Software Foundation, 59 Temple Place - Suite 330, > ; Boston, MA 02111-1307, USA. > > + #ifndef __PRO__ > .SPACE $PRIVATE$ > .SUBSPA $DATA$,QUAD=1,ALIGN=8,ACCESS=31 > .SUBSPA $BSS$,QUAD=1,ALIGN=8,ACCESS=31,ZERO,SORT=82 > *************** > *** 35,45 **** > .SUBSPA $LIT$,QUAD=0,ALIGN=8,ACCESS=44 > .SUBSPA $CODE$,QUAD=0,ALIGN=8,ACCESS=44,CODE_ONLY > .SUBSPA $MILLICODE$,QUAD=0,ALIGN=8,ACCESS=44,SORT=8 > ! > .IMPORT $$dyncall,MILLICODE > .SPACE $TEXT$ > .SUBSPA $CODE$ > ! > ; Simply call with the address of the desired import stub in %r22 and > ; arguments in the normal place (%r26-%r23 and stack slots). > ; > --- 36,49 ---- > .SUBSPA $LIT$,QUAD=0,ALIGN=8,ACCESS=44 > .SUBSPA $CODE$,QUAD=0,ALIGN=8,ACCESS=44,CODE_ONLY > .SUBSPA $MILLICODE$,QUAD=0,ALIGN=8,ACCESS=44,SORT=8 > ! #endif > .IMPORT $$dyncall,MILLICODE > + #ifndef __PRO__ > .SPACE $TEXT$ > .SUBSPA $CODE$ > ! #else > ! .text > ! #endif > ; Simply call with the address of the desired import stub in %r22 and > ; arguments in the normal place (%r26-%r23 and stack slots). > ; > Index: pa/t-pro > =================================================================== > RCS file: /cvs/gcc/gcc/gcc/config/pa/t-pro,v > retrieving revision 1.8 > diff -c -p -r1.8 t-pro > *** t-pro 2002/02/16 22:30:35 1.8 > --- t-pro 2002/03/26 16:57:10 > *************** T_ADAFLAGS=-mdisable-indexing > *** 2,7 **** > --- 2,11 ---- > > LIB2FUNCS_EXTRA=lib2funcs.asm > > + # The following macro definition is used to switch off usage of .SPACE > + # and .SUBSPACE pseudo-ops in lib2funcs.asm for elf targets. > + TARGET_LIBGCC2_CFLAGS=-D__PRO__ > + > # We want fine grained libraries, so use the new code to build the > # floating point emulation libraries. > FPBIT = fp-bit.c > > http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=3589 -- Joel Sherrill, Ph.D. Director of Research & Development joel@OARcorp.com On-Line Applications Research Ask me about RTEMS: a free RTOS Huntsville AL 35805 Support Available (256) 722-9985
