-// This .h file imports the code that causes tcmalloc to override libc |
-// versions of malloc/free/new/delete/etc. That is, it provides the |
-// logic that makes it so calls to malloc(10) go through tcmalloc, |
-// rather than the default (libc) malloc. |
-// |
-// This file also provides a method: ReplaceSystemAlloc(), that every |
-// libc_override_*.h file it #includes is required to provide. This |
-// is called when first setting up tcmalloc -- that is, when a global |
-// constructor in tcmalloc.cc is executed -- to do any initialization |
-// work that may be required for this OS. (Note we cannot entirely |
-// control when tcmalloc is initialized, and the system may do some |
-// mallocs and frees before this routine is called.) It may be a |
-// noop. |
-// |
-// Every libc has its own way of doing this, and sometimes the compiler |
-// matters too, so we have a different file for each libc, and often |
-// for different compilers and OS's. |
