Using floating point on such a 39# configuration is generally inadvisable, but we got to provide support 40# somehow so that we can run the testsuites. 41# fp-hack.h / dp-hack.h take care of slecting the parts that are needed, 42# and (for debugging) of renaming functions so that they can be 43# used in an asm wrapper. 44 45LIB2ADD = fp-bit.c dp-bit.c 46 47dp-bit.c: $(srcdir)/fp-bit.c 48 echo '#ifndef __big_endian__' > dp-bit.c 49 echo '#define FLOAT_BIT_ORDER_MISMATCH' >> dp-bit.c 50 echo '#endif' >> dp-bit.c 51 echo '#include "fp-bit.h"' >> dp-bit.c 52 echo '#include "config/arc/dp-hack.h"' >> dp-bit.c 53 grep -v 'include.*fp-bit.h' $(srcdir)/fp-bit.c >> dp-bit.c 54 55fp-bit.c: $(srcdir)/fp-bit.c 56 echo '#define FLOAT' > fp-bit.c 57 echo '#ifndef __big_endian__' >> fp-bit.c 58 echo '#define FLOAT_BIT_ORDER_MISMATCH' >> fp-bit.c 59 echo '#endif' >> fp-bit.c 60 echo '#include "config/arc/fp-hack.h"' >> fp-bit.c 61 cat $(srcdir)/fp-bit.c >> fp-bit.c 62 63# .init/.fini section routines 64 65crtg.o: $(srcdir)/config/arc/crtg.S 66 $(crt_compile) -c -x assembler-with-cpp $< 67 68crtgend.o: $(srcdir)/config/arc/crtgend.S 69 $(crt_compile) -c -x assembler-with-cpp $< 70 71mcount.o: $(srcdir)/config/arc/gmon/mcount.c 72 $(gcc_compile) -isystem $(srcdir)/config/arc/gmon -c $< \ 73 -fcall-saved-r0 -fcall-saved-r1 -fcall-saved-r2 -fcall-saved-r3 \ 74 -fcall-saved-r4 -fcall-saved-r5 -fcall-saved-r6 -fcall-saved-r7 \ 75 -fomit-frame-pointer 76 77gmon.o: $(srcdir)/config/arc/gmon/gmon.c 78 $(gcc_compile) -isystem $(srcdir)/config/arc/gmon -mno-sdata -c $< \ 79 -fno-strict-aliasing \ 80 -Wno-extra # suppress inane warning about missing initializer. 81 # Adding initializers for the remaining elements of gmonparam would 82 # make the code more brittle. 83 84prof-freq-stub.o: $(srcdir)/config/arc/gmon/prof-freq-stub.S 85 $(gcc_compile) -isystem $(srcdir)/config/arc/gmon -c $< 86 87prof-freq.o: $(srcdir)/config/arc/gmon/prof-freq.c 88 $(gcc_compile) -isystem $(srcdir)/config/arc/gmon -c $< 89 90dcache_linesz.o: $(srcdir)/config/arc/gmon/dcache_linesz.S 91 $(gcc_compile) -isystem $(srcdir)/config/arc/gmon -c $< 92 93profil.o: $(srcdir)/config/arc/gmon/profil.S 94 $(gcc_compile) -isystem $(srcdir)/config/arc/gmon -c $< 95 96profil-uclibc.o: $(srcdir)/config/arc/gmon/profil-uclibc.c 97 $(gcc_compile) -isystem $(srcdir)/config/arc/gmon -c $< 98 99libgmon.a: mcount.o gmon.o dcache_linesz.o $(PROFILE_OSDEP) 100 $(AR_CREATE_FOR_TARGET) $@ $^ 101
