98 /* Public options. Some are compile-time only, some are run-time only, and some
99 are both. Most of the compile-time options are saved with the compiled regex so
100 that they can be inspected during studying (and therefore JIT compiling). Note
101 that pcre_study() has its own set of options. Originally, all the options
102 defined here used distinct bits. However, almost all the bits in a 32-bit word
103 are now used, so in order to conserve them, option bits that were previously
104 only recognized at matching time (i.e. by pcre_exec() or pcre_dfa_exec()) may
105 also be used for compile-time options that affect only compiling and are not
106 relevant for studying or JIT compiling.
107
108 Some options for pcre_compile() change its behaviour but do not affect the
109 behaviour of the execution functions. Other options are passed through to the
110 execution functions and affect their behaviour, with or without affecting the
111 behaviour of pcre_compile().
112
113 Options that can be passed to pcre_compile() are tagged Cx below, with these
114 variants:
115
116 C1 Affects compile only
117 C2 Does not affect compile; affects exec, dfa_exec
118 C3 Affects compile, exec, dfa_exec
119 C4 Affects compile, exec, dfa_exec, study
120 C5 Affects compile, exec, study
121
122 Options that can be set for pcre_exec() and/or pcre_dfa_exec() are flagged with
123 E and D, respectively. They take precedence over C3, C4, and C5 settings passed
124 from pcre_compile(). Those that are compatible with JIT execution are flagged
125 with J. */
