2013-03-11Avoid invalid pointer to pointer conversions.Pedro Alves1-14/+16
Casts between 'char **' <-> 'unsigned char **' and 'char **' <-> const char **' are actually invalid: http://gcc.gnu.org/ml/gcc-help/2013-03/msg00118.html In a nutshell, char (and variants) can alias anything, but pointers to chars get no special treatment (cf. C99/N1256, 6.5/7). Turns out older gcc's actually warn/complain on these constructs, though newer one's don't: http://sourceware.org/ml/gdb-patches/2013-03/msg00429.html http://sourceware.org/ml/gdb-patches/2013-03/msg00430.html This patch fixes the cases I added last week. It also fixes one other preexisting case in charset.c, though it seems even older gccs don't complain of char * <-> const char * aliasing. Tested on x86_64 Fedora 17. gdb/ 2013-03-11 Pedro Alves <palves@redhat.com> * charset.c (convert_between_encodings): Don't cast between different pointer to pointer types. Instead, make the 'inp' local be of the type iconv expects. (wchar_iterate): Don't cast between different pointer to pointer types. Instead, use new pointer local of the type iconv expects. * target.c (target_read_stralloc, target_fileio_read_stralloc): Add new local of type char pointer, and use it to get a char/string view of the byte buffer, instead of casting between pointer to pointer types.

2013-03-07target.c: fix -Wpointer-signPedro Alves1-6/+8
$ make WERROR_CFLAGS="-Wpointer-sign -Werror" target.o -k 2>&1 1>/dev/null ../../src/gdb/target.c: In function ‘target_read_stralloc’: ../../src/gdb/target.c:2376:3: error: pointer targets in passing argument 1 of ‘strlen’ differ in signedness [-Werror=pointer-sign] In file included from build-gnulib/import/string.h:27:0, from ../../src/gdb/common/gdb_string.h:24, from ../../src/gdb/target.c:24: /usr/include/string.h:399:15: note: expected ‘const char *’ but argument is of type ‘gdb_byte *’ ... This is about the same as the previous patch. Functions that take or return ascii-ish string arguments usually use char* for parameters/return. That means that at points we call into target methods that work with binary blobs, we need casts to/from gdb_byte*/char*. To choose which type for the variables, I usually go based on which requires the fewer casts, and what the contents of the variable are supposed to hold, which often gives the same answer. gdb/ 2013-03-07 Pedro Alves <palves@redhat.com> * target.c (target_read_stralloc, target_fileio_read_alloc): *Cast pointer to 'gdb_byte *' in target call.
2013-03-01Use gdb_byte for bytes from the program being debugged.Pedro Alves1-1/+1
gdb_byte should be used for bytes from the program being debugged. We have many places using char or unsigned char instead all over the existing ports, and more ends up added over time due to copy/paste as new code is based on old code. I've greped the tree for "char buf[", and fixed all I found. Tested by building with --enable-targets=all. 2013-03-01 Pedro Alves <palves@redhat.com> Use gdb_byte for bytes from the program being debugged. * arm-tdep.c (arm_store_return_value, arm_get_longjmp_target): Change type of local 'buf' to gdb_byte. * avr-tdep.c (avr_frame_prev_register, avr_push_dummy_call): Likewise. * bfin-tdep.c (bfin_push_dummy_call): Likewise. * cris-tdep.c (cris_sigcontext_addr) (cris_sigtramp_frame_unwind_cache): Likewise. * frv-linux-tdep.c (frv_linux_pc_in_sigtramp) (frv_linux_sigcontext_reg_addr, frv_linux_sigtramp_frame_cache): Likewise. * frv-tdep.c (frv_pseudo_register_write, frv_analyze_prologue): Likewise. * hppa-hpux-tdep.c (hppa32_hpux_find_global_pointer) (hppa32_hpux_search_dummy_call_sequence) (hppa_hpux_supply_save_state): Likewise. * hppa-linux-tdep.c (insns_match_pattern) (hppa_linux_find_global_pointer): Likewise. * hppa-tdep.c (hppa_in_function_epilogue_p) (skip_prologue_hard_way, hppa_frame_cache): Likewise. * i386-nto-tdep.c (i386nto_sigcontext_addr): Likewise. * i386fbsd-tdep.c (i386fbsd_supply_uthread) (i386fbsd_collect_uthread): Likewise. * ia64-hpux-tdep.c (ia64_hpux_push_dummy_code): Likewise. * ia64-linux-tdep.c (ia64_linux_sigcontext_register_address): Likewise. * ia64-tdep.c (examine_prologue, ia64_frame_cache) (ia64_frame_prev_register, ia64_sigtramp_frame_cache) (ia64_sigtramp_frame_prev_register, ia64_access_reg) (ia64_access_rse_reg, ia64_libunwind_frame_this_id) (ia64_libunwind_frame_prev_register) (ia64_libunwind_sigtramp_frame_this_id) (ia64_find_global_pointer_from_dynamic_section) (find_extant_func_descr, find_func_descr, ia64_dummy_id) (ia64_unwind_pc): Likewise. * iq2000-tdep.c (iq2000_store_return_value): Likewise. * m68hc11-tdep.c (m68hc11_push_dummy_call) (m68hc11_extract_return_value): Likewise. * m68klinux-nat.c (fetch_register, store_register): Likewise. * mep-tdep.c (mep_pseudo_cr32_read, mep_pseudo_cr32_write) (mep_get_insn, mep_push_dummy_call): Likewise. * mips-linux-tdep.c (mips_linux_get_longjmp_target) (mips_linux_in_dynsym_stub): Likewise. * mn10300-tdep.c (mep_pseudo_cr32_write): Likewise. * ppc-linux-nat.c (fetch_register, store_register): Likewise. * regcache.c (dump_endian_bytes): Change type of parameter 'buf' to gdb_byte. * remote-mips.c (mips_set_register): Likewise. * remote-sim.c (gdbsim_fetch_register): Likewise. * score-tdep.c (score7_fetch_inst): Change type of parameter 'memblock' and local 'buf' to gdb_byte.
