Fold historical *_types/_structs/_externs/_inlines splits where the layering is no longer load-bearing. - large_externs.h -> large.h: rename; it was a single-purpose function-prototype file. - background_thread_structs.h + background_thread_externs.h -> background_thread.h: merge. background_thread_inlines.h stays separate because it depends on arena_inlines_a.h. - bin_types.h -> bin.h: BIN_SHARDS_MAX / N_BIN_SHARDS_DEFAULT join the bin_t struct and the bin_dalloc_locked_info_t type. bin_inlines.h stays separate so TUs that only need the bin_t type don't pull in the tcache-flush inline closure. The two bin_stats_* helpers move from bin.h into bin_inlines.h so all bin inlines live together. - tsd_binshards.h (new): houses tsd_binshards_t and its zero initializer. Lets tsd_internals.h pull it in for X-macro expansion without dragging mutex.h -- mutex.h depends on TSD machinery, which would form a cycle through bin.h. jemalloc_internal_includes.h drops the references to the deleted/ merged headers.

/*
|
|
* jemalloc can conceptually be broken into components (arena, tcache, etc.),
|
|
* but there are circular dependencies that cannot be broken without
|
|
* substantial performance degradation.
|
|
*
|
|
* Historically, we dealt with this by each header into four sections (types,
|
|
* structs, externs, and inlines), and included each header file multiple times
|
|
* in this file, picking out the portion we want on each pass using the
|
|
* following #defines:
|
|
* JEMALLOC_H_TYPES : Preprocessor-defined constants and pseudo-opaque data
|
|
* types.
|
|
* JEMALLOC_H_STRUCTS : Data structures.
|
|
* JEMALLOC_H_EXTERNS : Extern data declarations and function prototypes.
|
|
* JEMALLOC_H_INLINES : Inline functions.
|
|
*
|
|
* We're moving toward a world in which the dependencies are explicit; each file
|
|
* will #include the headers it depends on (rather than relying on them being
|
|
* implicitly available via this file including every header file in the
|
|
* project).
|
|
*
|
|
* We're now in an intermediate state: we've broken up the header files to avoid
|
|
* having to include each one multiple times, but have not yet moved the
|
|
* dependency information into the header files (i.e. we still rely on the
|
|
* ordering in this file to ensure all a header's dependencies are available in
|
|
* its translation unit). Each component is now broken up into multiple header
|
|
* files, corresponding to the sections above (e.g. instead of "foo.h", we now
|
|
* have "foo_types.h", "foo_structs.h", "foo_externs.h", "foo_inlines.h").
|
|
*
|
|
* Those files which have been converted to explicitly include their
|
|
* inter-component dependencies are now in the initial HERMETIC HEADERS
|
|
* section. All headers may still rely on jemalloc_preamble.h (which, by fiat,
|
|
* must be included first in every translation unit) for system headers and
|
|
* global jemalloc definitions, however.
