/*

|
* mallinfo() stub for the mimalloc-allocator build.
|
||
|
|
*
|
||
|
|
* We link with -sMALLOC=mimalloc (per-thread heaps — needed so the parallel
|
||
|
|
* s-expr library parse doesn't serialize on dlmalloc's single global lock; see
|
||
|
|
* docs/features/libs/0013). Unlike emscripten's dlmalloc/emmalloc, mimalloc does
|
||
|
|
* NOT export the glibc memory-report API mallinfo()/mallinfo2(). OpenCASCADE's
|
||
|
|
* OSD_MemInfo.cxx (in libTKernel, linked only by pcbnew for 3D/STEP) references
|
||
|
|
* mallinfo(), so the pcbnew link fails with `undefined symbol: mallinfo` without
|
||
|
|
* this. (eeschema doesn't link OpenCASCADE, so it never needed it.)
|
||
|
|
*
|
||
|
|
* mallinfo() is used purely for optional memory reporting, so a zeroed result is
|
||
|
|
* harmless. Provided unconditionally (mirrors the nanosleep_yield / gl_ffp stub
|
||
|
|
* pattern); it's a no-op for apps that never reference it.
