From: Andrew Burgess Date: Fri, 20 Nov 2020 17:23:03 +0000 (+0000) Subject: gdbsupport: make use of safe-ctype functions from libiberty X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=96648494173;p=binutils-gdb.git gdbsupport: make use of safe-ctype functions from libiberty Make use of the safe-ctype replacements for the standard ctype character checking functions in gdbsupport/common-utils.cc. The gdbsupport library is included into both gdb and gdbserver, and on the gdbserver side there are two targets, gdbserver itself, and also libinproctrace.so. libiberty was already being included in the gdbserver link command, but was missing from the libinproctrace.so link. As a result, after changing gdbsupport/common-utils.cc to depend on libiberty, libinproctrace.so would no longer link until I modified its link line. gdbserver/ChangeLog: * Makefile.in (IPA_LIB): Include libiberty library. gdbsupport/ChangeLog: * gdbsupport/common-utils.cc: Change 'ctype.h' include to 'safe-ctype.h'. (extract_string_maybe_quoted): Use safe-ctype function versions. (is_digit_in_base): Likewise. (digit_to_int): Likewise. (strtoulst): Likewise. (skip_spaces): Likewise. (skip_to_space): Likewise. --- diff --git a/gdbserver/ChangeLog b/gdbserver/ChangeLog index 700da6ef871..9756d4cadaa 100644 --- a/gdbserver/ChangeLog +++ b/gdbserver/ChangeLog @@ -1,3 +1,7 @@ +2020-12-11 Andrew Burgess + + * Makefile.in (IPA_LIB): Include libiberty library. + 2020-11-11 Andrew Burgess * server.cc (gdbserver_usage): Add missing option to usage text. diff --git a/gdbserver/Makefile.in b/gdbserver/Makefile.in index 1969ed0ec37..e12848c1ce2 100644 --- a/gdbserver/Makefile.in +++ b/gdbserver/Makefile.in @@ -395,7 +395,7 @@ $(IPA_LIB): $(sort $(IPA_OBJS)) ${CDEPS} $(ECHO_CXXLD) $(CC_LD) -shared -fPIC -Wl,--soname=$(IPA_LIB) \ -Wl,--no-undefined $(INTERNAL_CFLAGS) $(INTERNAL_LDFLAGS) \ $(CXXFLAGS) \ - -o $(IPA_LIB) ${IPA_OBJS} -ldl -pthread + -o $(IPA_LIB) ${IPA_OBJS} $(LIBIBERTY) -ldl -pthread # Put the proper machine-specific files first, so M-. on a machine # specific routine gets the one for the correct machine. diff --git a/gdbsupport/ChangeLog b/gdbsupport/ChangeLog index 6be1f245bc5..cc21b0b50f0 100644 --- a/gdbsupport/ChangeLog +++ b/gdbsupport/ChangeLog @@ -1,3 +1,14 @@ +2020-12-11 Andrew Burgess + + * gdbsupport/common-utils.cc: Change 'ctype.h' include to + 'safe-ctype.h'. + (extract_string_maybe_quoted): Use safe-ctype function versions. + (is_digit_in_base): Likewise. + (digit_to_int): Likewise. + (strtoulst): Likewise. + (skip_spaces): Likewise. + (skip_to_space): Likewise. + 2020-12-11 Simon Marchi * common-debug.h (debug_prefixed_printf_cond): New. diff --git a/gdbsupport/common-utils.cc b/gdbsupport/common-utils.cc index b5e4d2928ec..4f5c26d075c 100644 --- a/gdbsupport/common-utils.cc +++ b/gdbsupport/common-utils.cc @@ -20,7 +20,7 @@ #include "common-defs.h" #include "common-utils.h" #include "host-defs.h" -#include +#include "safe-ctype.h" void * xzalloc (size_t size) @@ -177,7 +177,7 @@ extract_string_maybe_quoted (const char **arg) /* Parse p similarly to gdb_argv buildargv function. */ while (*p != '\0') { - if (isspace (*p) && !squote && !dquote && !bsquote) + if (ISSPACE (*p) && !squote && !dquote && !bsquote) break; else { @@ -230,21 +230,21 @@ extract_string_maybe_quoted (const char **arg) static int is_digit_in_base (unsigned char digit, int base) { - if (!isalnum (digit)) + if (!ISALNUM (digit)) return 0; if (base <= 10) - return (isdigit (digit) && digit < base + '0'); + return (ISDIGIT (digit) && digit < base + '0'); else - return (isdigit (digit) || tolower (digit) < base - 10 + 'a'); + return (ISDIGIT (digit) || TOLOWER (digit) < base - 10 + 'a'); } static int digit_to_int (unsigned char c) { - if (isdigit (c)) + if (ISDIGIT (c)) return c - '0'; else - return tolower (c) - 'a' + 10; + return TOLOWER (c) - 'a' + 10; } /* As for strtoul, but for ULONGEST results. */ @@ -258,7 +258,7 @@ strtoulst (const char *num, const char **trailer, int base) int i = 0; /* Skip leading whitespace. */ - while (isspace (num[i])) + while (ISSPACE (num[i])) i++; /* Handle prefixes. */ @@ -325,7 +325,7 @@ skip_spaces (char *chp) { if (chp == NULL) return NULL; - while (*chp && isspace (*chp)) + while (*chp && ISSPACE (*chp)) chp++; return chp; } @@ -337,7 +337,7 @@ skip_spaces (const char *chp) { if (chp == NULL) return NULL; - while (*chp && isspace (*chp)) + while (*chp && ISSPACE (*chp)) chp++; return chp; } @@ -349,7 +349,7 @@ skip_to_space (const char *chp) { if (chp == NULL) return NULL; - while (*chp && !isspace (*chp)) + while (*chp && !ISSPACE (*chp)) chp++; return chp; }
