190075Sobrien# 290075Sobrien# This file was based on t-sol2 - x68 Solaris implementation. Actually, 390075Sobrien# the source code to create crti.o anf crtn.o are exactly the same 490075Sobrien# as the ones for Solaris. Later, we might want to have a RTEMS's 590075Sobrien# version of these files. 690075Sobrien# 790075Sobrien 890075Sobriencrti.o: $(srcdir)/config/i386/sol2-ci.asm $(GCC_PASSES) 990075Sobrien sed -e '/^!/d' <$(srcdir)/config/i386/sol2-ci.asm >crti.s 1090075Sobrien $(GCC_FOR_TARGET) -c -o crti.o crti.s 1190075Sobriencrtn.o: $(srcdir)/config/i386/sol2-cn.asm $(GCC_PASSES) 1290075Sobrien sed -e '/^!/d' <$(srcdir)/config/i386/sol2-cn.asm >crtn.s 1390075Sobrien $(GCC_FOR_TARGET) -c -o crtn.o crtn.s 1490075Sobrien 1596263Sobrien# We want fine grained libraries, so use the new code to build the 1696263Sobrien# floating point emulation libraries. 1796263SobrienFPBIT = fp-bit.c 1896263SobrienDPBIT = dp-bit.c 1996263Sobrien 2096263SobrienLIB2FUNCS_EXTRA = xp-bit.c 2196263Sobrien 2296263Sobriendp-bit.c: $(srcdir)/config/fp-bit.c 2396263Sobrien echo '#ifdef __LITTLE_ENDIAN__' > dp-bit.c 2496263Sobrien echo '#define FLOAT_BIT_ORDER_MISMATCH' >>dp-bit.c 2596263Sobrien echo '#endif' >> dp-bit.c 2696263Sobrien cat $(srcdir)/config/fp-bit.c >> dp-bit.c 2796263Sobrien 2896263Sobrienfp-bit.c: $(srcdir)/config/fp-bit.c 2996263Sobrien echo '#define FLOAT' > fp-bit.c 3096263Sobrien echo '#ifdef __LITTLE_ENDIAN__' >> fp-bit.c 3196263Sobrien echo '#define FLOAT_BIT_ORDER_MISMATCH' >>fp-bit.c 3296263Sobrien echo '#endif' >> fp-bit.c 3396263Sobrien cat $(srcdir)/config/fp-bit.c >> fp-bit.c 3496263Sobrien 3596263Sobrienxp-bit.c: $(srcdir)/config/fp-bit.c 3696263Sobrien echo '#define EXTENDED_FLOAT_STUBS' > xp-bit.c 3796263Sobrien cat $(srcdir)/config/fp-bit.c >> xp-bit.c 3896263Sobrien 3996263SobrienMULTILIB_OPTIONS = mcpu=i486/mcpu=pentium/mcpu=pentiumpro/mcpu=k6/mcpu=athlon \ 4096263Sobrienmsoft-float mno-fp-ret-in-387 4196263SobrienMULTILIB_DIRNAMES= m486 mpentium mpentiumpro k6 athlon soft-float nofp 4296263SobrienMULTILIB_MATCHES = msoft-float=mno-m80387 4396263SobrienMULTILIB_EXCEPTIONS = \ 4496263Sobrienmno-fp-ret-in-387 \ 4596263Sobrienmcpu=i486/*mno-fp-ret-in-387* \ 4696263Sobrienmcpu=pentium/*msoft-float* mcpu=pentium/*mno-fp-ret-in-387* \ 4796263Sobrienmcpu=pentiumpro/*msoft-float* mcpu=pentiumpro/*mno-fp-ret-in-387* \ 4896263Sobrienmcpu=k6/*msoft-float* mcpu=k6/*mno-fp-ret-in-387* \ 4996263Sobrienmcpu=athlon/*msoft-float* mcpu=athlon/*mno-fp-ret-in-387* 5096263Sobrien 5196263SobrienEXTRA_MULTILIB_PARTS = crtbegin.o crtend.o 5296263Sobrien 5396263SobrienLIBGCC = stmp-multilib 5496263SobrienINSTALL_LIBGCC = install-multilib 55
