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