98 /* Public options. Some are compile-time only, some are run-time only, and some
99 are both, so we keep them all distinct. However, almost all the bits in the
100 options word are now used. In the long run, we may have to re-use some of the
101 compile-time only bits for runtime options, or vice versa. Any of the
102 compile-time options may be inspected during studying (and therefore JIT
103 compiling).
104
105 Some options for pcre_compile() change its behaviour but do not affect the
106 behaviour of the execution functions. Other options are passed through to the
107 execution functions and affect their behaviour, with or without affecting the
108 behaviour of pcre_compile().
109
110 Options that can be passed to pcre_compile() are tagged Cx below, with these
111 variants:
112
113 C1 Affects compile only
114 C2 Does not affect compile; affects exec, dfa_exec
115 C3 Affects compile, exec, dfa_exec
116 C4 Affects compile, exec, dfa_exec, study
117 C5 Affects compile, exec, study
118
119 Options that can be set for pcre_exec() and/or pcre_dfa_exec() are flagged with
120 E and D, respectively. They take precedence over C3, C4, and C5 settings passed
121 from pcre_compile(). Those that are compatible with JIT execution are flagged
122 with J. */
