From: Jarkko Hietaniemi Date: Sun, 17 Dec 2000 05:31:37 +0000 (+0000) Subject: Polymorphic regexps. X-Git-Tag: accepted/trunk/20130322.191538~33295 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ffc61ed20e8bcfd3f1fbed23f6b8ef5c02664323;p=platform%2Fupstream%2Fperl.git Polymorphic regexps. Fixes at least the bugs 20001028.003 (both of them...) and 20001108.001. The bugs 20001114.001 and 20001205.014 seem also to be fixed by now, probably already before this patch. p4raw-id: //depot/perl@8143 --- diff --git a/embed.h b/embed.h index 64c1eaf..3b54154 100644 --- a/embed.h +++ b/embed.h @@ -543,6 +543,7 @@ #define ref Perl_ref #define refkids Perl_refkids #define regdump Perl_regdump +#define regclass_swash Perl_regclass_swash #define pregexec Perl_pregexec #define pregfree Perl_pregfree #define pregcomp Perl_pregcomp @@ -995,7 +996,6 @@ #define regbranch S_regbranch #define reguni S_reguni #define regclass S_regclass -#define regclassutf8 S_regclassutf8 #define regcurly S_regcurly #define reg_node S_reg_node #define regpiece S_regpiece @@ -1025,7 +1025,6 @@ #define regrepeat_hard S_regrepeat_hard #define regtry S_regtry #define reginclass S_reginclass -#define reginclassutf8 S_reginclassutf8 #define regcppush S_regcppush #define regcppop S_regcppop #define regcp_set_to S_regcp_set_to @@ -2015,6 +2014,7 @@ #define ref(a,b) Perl_ref(aTHX_ a,b) #define refkids(a,b) Perl_refkids(aTHX_ a,b) #define regdump(a) Perl_regdump(aTHX_ a) +#define regclass_swash(a,b,c) Perl_regclass_swash(aTHX_ a,b,c) #define pregexec(a,b,c,d,e,f,g) Perl_pregexec(aTHX_ a,b,c,d,e,f,g) #define pregfree(a) Perl_pregfree(aTHX_ a) #define pregcomp(a,b,c) Perl_pregcomp(aTHX_ a,b,c) @@ -2459,7 +2459,6 @@ #define regbranch(a,b,c) S_regbranch(aTHX_ a,b,c) #define reguni(a,b,c,d) S_reguni(aTHX_ a,b,c,d) #define regclass(a) S_regclass(aTHX_ a) -#define regclassutf8(a) S_regclassutf8(aTHX_ a) #define regcurly(a) S_regcurly(aTHX_ a) #define reg_node(a,b) S_reg_node(aTHX_ a,b) #define regpiece(a,b) S_regpiece(aTHX_ a,b) @@ -2487,8 +2486,7 @@ #define regrepeat(a,b) S_regrepeat(aTHX_ a,b) #define regrepeat_hard(a,b,c) S_regrepeat_hard(aTHX_ a,b,c) #define regtry(a,b) S_regtry(aTHX_ a,b) -#define reginclass(a,b) S_reginclass(aTHX_ a,b) -#define reginclassutf8(a,b) S_reginclassutf8(aTHX_ a,b) +#define reginclass(a,b,c) S_reginclass(aTHX_ a,b,c) #define regcppush(a) S_regcppush(aTHX_ a) #define regcppop() S_regcppop(aTHX) #define regcp_set_to(a) S_regcp_set_to(aTHX_ a) @@ -3950,6 +3948,8 @@ #define refkids Perl_refkids #define Perl_regdump CPerlObj::Perl_regdump #define regdump Perl_regdump +#define Perl_regclass_swash CPerlObj::Perl_regclass_swash +#define regclass_swash Perl_regclass_swash #define Perl_pregexec CPerlObj::Perl_pregexec #define pregexec Perl_pregexec #define Perl_pregfree CPerlObj::Perl_pregfree @@ -4787,8 +4787,6 @@ #define reguni S_reguni #define S_regclass CPerlObj::S_regclass #define regclass S_regclass -#define S_regclassutf8 CPerlObj::S_regclassutf8 -#define regclassutf8 S_regclassutf8 #define S_regcurly CPerlObj::S_regcurly #define regcurly S_regcurly #define S_reg_node CPerlObj::S_reg_node @@ -4845,8 +4843,6 @@ #define regtry S_regtry #define S_reginclass CPerlObj::S_reginclass #define reginclass S_reginclass -#define S_reginclassutf8 CPerlObj::S_reginclassutf8 -#define reginclassutf8 S_reginclassutf8 #define S_regcppush CPerlObj::S_regcppush #define regcppush S_regcppush #define S_regcppop CPerlObj::S_regcppop diff --git a/embed.pl b/embed.pl index 9e2bd9c..32f3ddc 100755 --- a/embed.pl +++ b/embed.pl @@ -1873,6 +1873,7 @@ Ap |void |push_scope p |OP* |ref |OP* o|I32 type p |OP* |refkids |OP* o|I32 type Ap |void |regdump |regexp* r +Ap |SV* |regclass_swash |struct regnode *n|bool doinit|SV **initsvp Ap |I32 |pregexec |regexp* prog|char* stringarg \ |char* strend|char* strbeg|I32 minend \ |SV* screamer|U32 nosave @@ -2366,7 +2367,6 @@ s |regnode*|regatom |struct RExC_state_t*|I32 * s |regnode*|regbranch |struct RExC_state_t*|I32 *|I32 s |void |reguni |struct RExC_state_t*|UV|char *|STRLEN* s |regnode*|regclass |struct RExC_state_t* -s |regnode*|regclassutf8 |struct RExC_state_t* s |I32 |regcurly |char * s |regnode*|reg_node |struct RExC_state_t*|U8 s |regnode*|regpiece |struct RExC_state_t*|I32 * @@ -2401,8 +2401,7 @@ s |I32 |regmatch |regnode *prog s |I32 |regrepeat |regnode *p|I32 max s |I32 |regrepeat_hard |regnode *p|I32 max|I32 *lp s |I32 |regtry |regexp *prog|char *startpos -s |bool |reginclass |regnode *p|I32 c -s |bool |reginclassutf8 |regnode *f|U8* p +s |bool |reginclass |regnode *n|U8 *p|bool do_utf8sv_is_utf8 s |CHECKPOINT|regcppush |I32 parenfloor s |char*|regcppop s |char*|regcp_set_to |I32 ss diff --git a/mg.c b/mg.c index f97c6ce..a61d167 100644 --- a/mg.c +++ b/mg.c @@ -391,7 +391,7 @@ Perl_magic_len(pTHX_ SV *sv, MAGIC *mg) case '5': case '6': case '7': case '8': case '9': case '&': if (PL_curpm && (rx = PL_curpm->op_pmregexp)) { - paren = atoi(mg->mg_ptr);
