Make it possible to build a cross gprof, although a few cases are still not handled: * configure.in: Don't set MY_TARGET. * gprof.h: Don't include MACHINE_H. Don't define FOPEN_RB or FOPEN_WB; just get them from sysdep.h. * core.h (min_insn_size, offset_to_code): Declare. * core.c (MIN_INSN_SIZE): Don't define. (min_insn_size, offset_to_code): New variables. (core_init): Initialize min_insn_size and offset_to_code. (find_call): New function. (core_create_line_syms): Don't use min_dist. Set is_static in pass 2. * hist.c (UNITS_TO_CODE): Define. * gprof.c (default_excluded_list): Add "__mcount_internal". * gmon.h: Change TARGET_alpha to __alpha__. * hertz.h: Ifdef MACH, define hertz as HZ. * alpha.c (alpha_Instruction): Rename from Instruction. Change all references. (alpha_find_call): Rename from find_call. * alpha.h: Remove. * dummy.c, dummy.h: Remove. * i386.c (i386_iscall): Rename from iscall. Change all references. Check for call instruction, not jump or lcall. (i386_find_call): Rename from find_call. Correct for VMA. Correct call destination computation. Don't dereference symbol if it is NULL. * i386.h: Remove. * ns532.c, ns532.h: Remove. * sparc.c (CALL): Define. (sparc_find_call): Rename from find_call. * sparc.h: Remove. * tahoe.c: Include cg_arcs.h, core.h, hist.h, and symtab.h. Don't include time_host.h. (CALLF, PC): Define. (enum tahoe_opermodes, tahoe_operandenum): Define. Rename all references to opermodes or operandenum to these. (tahoe_operandmode): Rename from operandmode. Call abort if switch does not return. (tahoe_operandname): Rename from operandname. Call abort if switch does not return. (tahoe_operandlength): Rename from operandlength. Call abort if switch does not return. (tahoe_reladdr): Rename from reladdr. (tahoe_find_call): Rename from find_call. Use core_text_space rather than textspace. * tahoe.h: Remove. * vax.c (CALLS, PC): Define. (enum opermodes, operandenum, struct modebyte): Define. (vax_operandmode): Rename from operandmode. Call abort if switch does not return. (vax_operandname): Rename from operandname. Call abort if switch does not return. (vax_operandlength): Rename from operandlength. Call abort if switch does not return. (vax_reladdr): Rename from reladdr. (vax_find_call): Rename from find_call. * vax.h: Remove. * Makefile.am (AUTOMAKE_OPTIONS): Set to cygnus. (MY_TARGET): Remove. (INCLUDES): Remove -DTARGET_$(MY_TARGET) and -DMACHINE_H= \"$(MY_TARGET).h\". (gprof_SOURCES): Add i386.c, alpha.c, vax.c, tahoe.c, sparc.c. (gprof_DEPENDENCIES): Remove $(MY_TARGET).o. (gprof_LDADD): Likewise. (noinst_HEADERS): Remove alpha.h, i386.h, ns532.h, sparc.h, tahoe.h, vax.h, dummy.h. (EXTRA_DIST): Remove alpha.c, i386.c, ns532.c, sparc.c, tahoe.c, vax.c, dummy.c. ($(OBJECTS)): Don't depend upon $(MY_TARGET).h. ($(MY_TARGET).o): Remove target. (i386.o, alpha.o, vax.o, tahoe.o, sparc.o): New targets. * configure, Makefile.in, aclocal.m4: Rebuild.
