RS/6000 portability changes (for hosting cross-debuggers).
* breakpoint.c (fixup_breakpoints): Re-kludge to IBM6000_TARGET.
* buildsym.c, rs6000-xdep.c, rs6000-tdep.c, tm-rs6000.h,
xcoffexec.c, xcoffread.c: Rename aixcoff to xcoff everywhere.
* printcmd.c (print_frame_args): Remove an RS/6000 dependency.
* stabsread.c (define_symbol): Remove RS/6000 dependencies.
* tm-rs6000.h (ATTACH_DETACH): Remove: host-dependent.
(PTRACE_ATTACH, PTRACE_DETACH): Remove: host-dep.
(NO_SINGLE_STEP): Add, target-dependent.
(loadinfotextindex): Lowercase, remove "aix_".
* xm-rs6000.h: Add <sys/ptrace.h> for infptrace.c.
(NO_SINGLE_STEP): Remove, target-dependent.
* xcoffexec.c (vmap_symtab): Cleanup #if 0'd code.
* xcoffread.c: Only build file if RS/6000 native GDB.
(build_function_symbol): Remove #if 0'd code.
* rs6000-tdep.c: Cleanup. Add static fn protos.
Use CORE_ADDR for addresses throughout. Make void fns void.
(pop_dummy_frame): Add FIXME about bogosity of design here.
(rs6000_struct_return_address): Ditto.

frame_initial_stack_address, xcoff_relocate_symtab,

/* Read AIX xcoff symbol tables and convert to internal format, for GDB.
|
* eval.c (evaluate_subexp): Make fnptr a LONGEST instead
of using longest_to_int.
* infcmd.c (run_stack_dummy): Reinstate set_current_frame call,
mips and alpha targets need the real breakpoint pc for
creating the breakpoint frame.
* stack.c (return_command): Cast return value to the return
type of the function from which we return.
* values.c (set_return_value): Pass VALUE_CONTENTS unmodified
to STORE_RETURN_VALUE.
* symtab.c (lookup_symbol): Remove search for `static mangled
symbols', the search for `static symbols' already looks for
mangled and demangled symbols via lookup_block_symbol.
* valarith.c (value_binop): Use ANSI C arithmetic conversions
when performing integral evaluations, implement BINOP_EQUAL and
BINOP_LESS.
(value_equal, value_less): Use value_binop to perform the
comparison if both operands have TYPE_CODE_INT.
* rs6000-tdep.c (pop_frame): Make sure all registers are valid,
as they are written back later. Handle sp restore for frameless
functions. Use fdata.nosavedpc instead of fdata.frameless to
determine if the pc has been saved.
(function_frame_info): Handle `mr r31,r1', which is generated by
gcc-2.6, as a synonym for `oril r31,r1,0'.
(skip_trampoline_code): Handle shared library trampolines.
* xcoffread.c (read_xcoff_symtabs): Record XMC_GL symbols with
their real name. Enables setting of breakpoints in shared libraries
before the executable is run.

Two reasons:
|
|
|
|
|
|
|
|
|
|
1) xlc (IBM's native c compiler) postpones static function code
|
|
|
|
|
emission to the end of a compilation unit. This way it can
|
|
|
|
|
determine if those functions (statics) are needed or not, and
|
|
|
|
|
can do some garbage collection (I think). This makes line
|
|
|
|
|
numbers and corresponding addresses unordered, and we end up
|
|
|
|
|
with a line table like:
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
lineno addr
|
|
|
|
|
foo() 10 0x100
|
|
|
|
|
20 0x200
|
|
|
|
|
30 0x300
|
|
|
|
|
|
|
|
|
|
foo3() 70 0x400
|
|
|
|
|
80 0x500
|
|
|
|
|
90 0x600
|
|
|
|
|
|
|
|
|
|
static foo2()
|
|
|
|
|
40 0x700
|
|
|
|
|
50 0x800
|
|
|
|
|
60 0x900
|
|
|
|
|
|
|
|
|
|
and that breaks gdb's binary search on line numbers, if the
|
|
|
|
|
above table is not sorted on line numbers. And that sort
|
|
|
|
|
should be on function based, since gcc can emit line numbers
|
|
|
|
|
like:
|
|
|
|
|
|
|
|
|
|
10 0x100 - for the init/test part of a for stmt.
|
|
|
|
|
20 0x200
|
|
|
|
|
30 0x300
|
|
|
|
|
10 0x400 - for the increment part of a for stmt.
|
1991-11-12 15:24:56 +00:00
|
|
|
|
|
1993-04-26 14:20:57 +00:00
|
|
|
|
arrange_linetable() will do this sorting.
|

|
|

|
|
1993-04-26 14:20:57 +00:00

RS/6000 portability changes (for hosting cross-debuggers).
* breakpoint.c (fixup_breakpoints): Re-kludge to IBM6000_TARGET.
* buildsym.c, rs6000-xdep.c, rs6000-tdep.c, tm-rs6000.h,
xcoffexec.c, xcoffread.c: Rename aixcoff to xcoff everywhere.
* printcmd.c (print_frame_args): Remove an RS/6000 dependency.
* stabsread.c (define_symbol): Remove RS/6000 dependencies.
* tm-rs6000.h (ATTACH_DETACH): Remove: host-dependent.
(PTRACE_ATTACH, PTRACE_DETACH): Remove: host-dep.
(NO_SINGLE_STEP): Add, target-dependent.
(loadinfotextindex): Lowercase, remove "aix_".
* xm-rs6000.h: Add <sys/ptrace.h> for infptrace.c.
(NO_SINGLE_STEP): Remove, target-dependent.
* xcoffexec.c (vmap_symtab): Cleanup #if 0'd code.
* xcoffread.c: Only build file if RS/6000 native GDB.
(build_function_symbol): Remove #if 0'd code.
* rs6000-tdep.c: Cleanup. Add static fn protos.
Use CORE_ADDR for addresses throughout. Make void fns void.
(pop_dummy_frame): Add FIXME about bogosity of design here.
(rs6000_struct_return_address): Ditto.
(frameless_function_invocation, frame_get_cache_fsr,
frame_initial_stack_address, xcoff_relocate_symtab,
xcoff_init_loadinfo, free_loadinfo, xcoff_add_toc_to_loadinfo,
add_text_to_loadinfo, find_toc_address): Move from xdep file.
Use CORE_ADDRs. Change identifiers to lowercase.
* rs6000-xdep.c: Make whole file conditional on native RS/6000,
supplying dummy routines if non-native. Add prototype for
static exec_one_dummy_insn. Move a mess of functions to
rs6000-tdep.c (as above). Remove #if 0'd code.
* config/rs6000.mh (XDEPFILES): Move xcoffexec.o to target side.
(XM_CLIBS): Add -lm to circumvent AIX 3.2 libc ldexp bug.
* config/rs6000.mt (TDEPFILES): Adopt xcoffexec.o.

the BFD for the file whose symbols are being read, and a slot for

a pointer to "private data" which we fill with cookies and other

Add sym_finish function pointer and change prototypes of other
function pointers to reflect passing struct objfile pointer rather
than struct sym_fns pointer.
* symfile.c: Remove now obsolete symtab_fns pointer.
* symfile.c (symfile_init): Renamed to find_sym_fns, and now only
locates the correct sym_fns struct for the given objfile.
* symfile.c (syms_from_objfile, symbol_file_add): Restructured
for better support of mapped symbol tables.
* symfile.c (symbol_file_command): Remove obsolete code using
symfile_fns.
* symfile.h: Remove duplicate declarations for symfile_objfile,
entry_point, and object_files.
* target.c (target_info): Compare symfile_objfile to NULL.
* xcoffread.c (aixcoff_new_init): Move deallocation stuff to
aixcoff_symfile_finish().

frame_initial_stack_address, xcoff_relocate_symtab,
xcoff_init_loadinfo, free_loadinfo, xcoff_add_toc_to_loadinfo,
add_text_to_loadinfo, find_toc_address): Move from xdep file.
Use CORE_ADDRs. Change identifiers to lowercase.
* rs6000-xdep.c: Make whole file conditional on native RS/6000,
supplying dummy routines if non-native. Add prototype for
static exec_one_dummy_insn. Move a mess of functions to
rs6000-tdep.c (as above). Remove #if 0'd code.
* config/rs6000.mh (XDEPFILES): Move xcoffexec.o to target side.
(XM_CLIBS): Add -lm to circumvent AIX 3.2 libc ldexp bug.
* config/rs6000.mt (TDEPFILES): Adopt xcoffexec.o.
