Each component is now broken up into multiple header 29 * files, corresponding to the sections above (e.g. instead of "foo.h", we now 30 * have "foo_types.h", "foo_structs.h", "foo_externs.h", "foo_inlines.h"). 31 * 32 * Those files which have been converted to explicitly include their 33 * inter-component dependencies are now in the initial HERMETIC HEADERS 34 * section. All headers may still rely on jemalloc_preamble.h (which, by fiat, 35 * must be included first in every translation unit) for system headers and 36 * global jemalloc definitions, however. 37 */ 38 39 /******************************************************************************/ 40 /* TYPES */ 41 /******************************************************************************/ 42 43 #include "jemalloc/internal/arena_types.h" 44 #include "jemalloc/internal/tcache_types.h" 45 #include "jemalloc/internal/prof_types.h" 46 47 /******************************************************************************/ 48 /* STRUCTS */ 49 /******************************************************************************/ 50 51 #include "jemalloc/internal/prof_structs.h" 52 #include "jemalloc/internal/arena_structs.h" 53 #include "jemalloc/internal/tcache_structs.h" 54 #include "jemalloc/internal/background_thread_structs.h" 55 56 /******************************************************************************/ 57 /* EXTERNS */ 58 /******************************************************************************/ 59 60 #include "jemalloc/internal/jemalloc_internal_externs.h" 61 #include "jemalloc/internal/arena_externs.h" 62 #include "jemalloc/internal/large_externs.h" 63 #include "jemalloc/internal/tcache_externs.h" 64 #include "jemalloc/internal/prof_externs.h" 65 #include "jemalloc/internal/background_thread_externs.h" 66 67 /******************************************************************************/ 68 /* INLINES */ 69 /******************************************************************************/ 70 71 #include "jemalloc/internal/jemalloc_internal_inlines_a.h" 72 /* 73 * Include portions of arena code interleaved with tcache code in order to 74 * resolve circular dependencies. 75 */ 76 #include "jemalloc/internal/arena_inlines_a.h" 77 #include "jemalloc/internal/jemalloc_internal_inlines_b.h" 78 #include "jemalloc/internal/tcache_inlines.h" 79 #include "jemalloc/internal/arena_inlines_b.h" 80 #include "jemalloc/internal/jemalloc_internal_inlines_c.h" 81 #include "jemalloc/internal/prof_inlines.h" 82 #include "jemalloc/internal/background_thread_inlines.h" 83 84 #endif /* JEMALLOC_INTERNAL_INCLUDES_H */ 85
