| # Recent versions of automake (1.5 and up for instance) append automake |
| # generated suffixes to this $(SUFFIXES) list. This is essential for us, |
| # since .c must come after .s, .S and .asm. If .c is before .s, for |
| # instance, then in the mpn directory "make" will see add_n.c mentioned in |
| # an explicit rule (the ansi2knr stuff) and decide it must have add_n.c, |
| # even if add_n.c doesn't exist but add_n.s does. See GNU make |
| # documentation "(make)Implicit Rule Search", part 5c. |
| # |
| # On IRIX 6 native make this doesn't work properly though. Somehow .c |
| # remains ahead of .s, perhaps because .c.s is a builtin rule. .asm works |
| # fine though, and mpn/mips3 uses this. |

| # It's necessary to run $(CPP) separately, since it seems not all compilers |
| # recognise .S files, in particular "cc" on HP-UX 10 and 11 doesn't (and |
| # will silently do nothing if given a .S). |
| # |

| # .asm assembler, preprocessed with m4. |
| # |
| # .o and .obj are non-PIC and just need m4 followed by a compile. |
| # |
| # .lo is a bit tricky. Libtool (as of version 1.5) has foo.lo as a little |
| # text file, and .libs/foo.o and foo.o as the PIC and non-PIC objects, |
| # respectively. It'd be asking for lots of trouble to try to create foo.lo |
| # ourselves, so instead arrange to invoke libtool like a --mode=compile, but |
| # with a special m4-ccas script which first m4 preprocesses, then compiles. |
| # --tag=CC is necessary since foo.asm is otherwise unknown to libtool. |
| # |
| # Libtool adds -DPIC when building a shared object and the .asm files look |
| # for that. But it should be noted that the other PIC flags are on occasion |
| # important too, in particular FreeBSD 2.2.8 gas 1.92.3 requires -k before |
| # it accepts PIC constructs like @GOT, and gcc adds that flag only under |
| # -fPIC. (Later versions of gas are happy to accept PIC stuff any time.) |
