void mi_free_csize (void *p, size_t size)

Detailed Description

Constant size allocation and freeing For example:

-
long* p = (long*)mi_malloc_csize(sizeof(long))
+

Inlined definitions for onstant size allocation and freeing.

+

If the size is constant, it can pick statically between mi_malloc() and mi_malloc_small(). For example:

long* p = (long*)mi_malloc_csize(sizeof(long))
mi_malloc_csize
void * mi_malloc_csize(size_t size)
Allocate a constant size object.
-

On v3 these can improve performance as they will statically use mi_malloc_small(), mi_free_small(), etc. when possible. This is especially useful for compilers and runtimes where the the size is often statically known. These functions can be used even when the size is not constant but then there is no performance benefit.

Checked free: just as mi_free but always checks if the pointer p belongs to our heap and is safe to use when a pointer might be invalid or allocated by another allocator.

Detailed Description

Typed allocation macros.

For example:

int* p = mi_malloc_tp(int)
-
mi_malloc_tp
#define mi_malloc_tp(tp)
Allocate a block of type tp.
Definition mimalloc-doc.h:364
+
mi_malloc_tp
#define mi_malloc_tp(tp)
Allocate a block of type tp.
Definition mimalloc-doc.h:373

On v3 these can improve performance as they use the mi_<malloc>_csize api's that in turn can use mi_malloc_small(), mi_free_small(), etc.

Detailed Description

Inlined definitions for onstant size allocation and freeing.

If the size is constant, it can pick statically between mi_malloc() and mi_malloc_small(). For example:

long* p = (long*)mi_malloc_csize(sizeof(long))
-
mi_malloc_csize
void * mi_malloc_csize(size_t size)
Allocate a constant size object.
+
mi_malloc_csize
void * mi_malloc_csize(size_t size)
v3: Allocate a constant size object.

On v3 these can improve performance. This is especially useful for compilers and runtimes where the the size is often statically known. These functions can be used even when the size is not constant but then there is no performance benefit.

For example: +Consider the following build options (v3): -``` -> gcc -o myprogram mimalloc.o myfile1.c ... -``` +- `-DMI_OPT_ARCH=ON` (by default ON on arm64): enables architecture specific optimizations. + This uses `-march=haswell;-march=avx2` on x64 (available since 2013), `-march=armv8.1` on arm64 (2016), + and `-march=rv64gcb_zacas` on riscV (2023). + Each benefits mimalloc with better bit operations and/or native atomic operations (but also, if your + emulator or hardware does not support these extensions the program will fail with an illegal instruction). + On Apple arm64 the default is `-march=armv8.3` (which is supported on the M1 and better) which includes + efficient load-acquire instructions which mimalloc uses. For riscV the corresponding `zalasr` extension + can be enabled as `-DMI_OPT_ARCH=rv64gcb_zacas_zalasr` when your hardware supports it. -Another way to override statically that works on all platforms, is to -link statically to mimalloc (as shown in the introduction) and include a -header file in each source file that re-defines `malloc` etc. to `mi_malloc`. -This is provided by [`mimalloc-override.h`](include/mimalloc-override.h). This only works -reliably though if all sources are -under your control or otherwise mixing of pointers from different heaps may occur! +- `-DMI_ALLOW_THP=OFF`: disabling THP can reduce the rss of certain programs significantly. + +- `-DMI_ALLOW_THP=FULL`: enabling THP can increase performance of certain programs significantly. This setting + still disables THP if the OS THP setting is configured as `[never]`. + +- `-DMI_FREE_IS_CHECKED=ON` (by default ON in secure mode): slightly slower performance but checks validity + of every pointer passed to `mi_free`. Sometimes needed when overriding malloc/free process wide. + Note also that `mi_cfree` (checked free) always checks the validity of pointers passed to it which can + also be used if appropiate without needing to check all pointers process wide. + +In the source code: + +- Use `mi_zalloc` for zero initialized allocations. + +- Use the typed macros `mi_malloc_tp` etc. as these are both more safe and also use `mi_malloc_csize` internally. + +- Use `mi_malloc_csize`/`mi_free_csize` etc. when the allocated or free'd size is a constant as these are inlined + and statically redirect to `mi_malloc_small`/`mi_free_small` when possible. + These are also used by the C++ `mimalloc-new-delete.h` sized overrides. + You can use `mi_free_csize_nonnull` when the pointer is guaranteed to be not `NULL` as well. + +- Use `mi_malloc_small` when the allocation size is guaranteed to be less than `MI_SMALL_SIZE_MAX` (1KiB) for faster allocations. + +- Use `mi_free_small` when the pointer was returned from `mi_malloc_small` (and guaranteed to have a + size of less than `MI_SMALL_SIZE_MAX`). Use `mi_free_small_nonnull` when the pointer is guaranteed to be not `NULL` as well. + +For run-time systems and compilers (like Koka, Lean, etc.), we can do slightly better still. + +- If the allocation size is statically known, use `mi_malloc_csize` and `mi_free_csize` etc. when possible. + (or directly `mi_malloc_small`/`mi_free_small`). + +- If the runtime already carries thread local state, it may be faster to get the default `theap` for each thread + up-front (`mi_theap_get_default()`) and use the very fast `mi_theap_malloc(_small)` etc. passing the theap + pointer directly. This avoids having mimalloc look up the thread local pointer all the time. Whether this is + faster depends a bit on the OS implementation of thread local variables. -Note: recently we also enabled static overloading on Windows. In that case you need -to link with the static CRT _release_ runtime (`/MT`) and link with the static -`mimalloc(-debug).obj` (to take precendence over the definitions in the CRT library). # Tools @@ -662,9 +716,11 @@ use a tool like [TraceControl] that is specialized for analyzing mimalloc traces [TraceControl]: https://github.com/xinglonghe/TraceControl + # Performance -Last update: 2021-01-30 +Last update: 2021-01-30. +(Note 2026-09-01: this is a while ago now, many of these allocators have improved over time as well.
