Revert r1.286 now that all supported platforms have __builtin_clz.

is clearly only for VM_MALLOC_CONF, but takes

care of doing that include.

When commons were deprecated, noone noticed that malloc_options in static

2025-05-23T00:40:05+00:00

binaries had become unlinkable. Change the libc definition to weak to solve that, and to "const char * const" so that noone will try to set it late. It must be stable before the first malloc() call, which could be before main()... discussion with otto, kettenis, tedu

In _malloc_init(), round up the region being mprotected RW to the malloc

page size, rather than relying upon mprotect to round up to the actual mmu page size. This repairs malloc operation on systems where the malloc page size (1 << _MAX_PAGE_SHIFT) is larger than the mmu page size. ok otto@

A small cleanup of malloc_bytes(), getting rid of a goto and a tiny

malloc option D (aka 1), 2, 3 or 4. No performance impact if not used. ok asou@

KNF plus fixed a few signed vs unsigned compares (that we actually

not real problems)

A few micro-optimizations; ok asou@

When option D is active, store callers for all chunks; this avoids

2023-10-22T12:19:26+00:00

the 0x0 call sites for leak reports. Also display more info on detected write of free chunks: print the info about where the chunk was allocated, and for the preceding chunk as well. ok asou@
