* Avoid doing a memset on a non-POD structuretrav902018-08-18-13/+33
| | | | | | |entryCount| tracks -- in fast-to-check manner -- the number of entries in the hashtable. But to actually enumerate entries, we have to loop through all of |table|, checking for entries that are actually live. A live entry is indicated by a zero |hash| in the entry. The |memset| would properly zero that; removing the memset will not. It's not entirely clear whether a memset that overwrites a lot of stuff but is maybe simpler, is faster than compiler-generated likely-SIMD code that zeroes out *just* |hash| fields in all the entries. But I am going to guess that SIMD is good enough. For now, we should just do the simple and thing: don't distinguish POD and non-POD, and know that the compiler is going to recognize that |mem.addr()->~T()| is a no-op when T is trivial. So with POD, the loop should degenerate to just zeroing |hash| at consistent offset, and SIMD will eat that up, and it can't be *that* different from the memset in performance (if it is at all).

| | | | | | | | This removes the constructors, which were never called since we allocate arrays of HeapSlot with pod_malloc. The destructor is only ever called explicitly since we free this memory with js_free so it has been renamed to destroy(). Also removed is an unused manual barrier.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UXP uses the current stack frame address and the stack size as a sort of heuristic for various things in the JavaScript engine. The js::GetNativeStackBaseImpl() function is used to get the base stack address (i.e. the address from which the stack grows, so this can be either the first or last memory address of the stack memory space depending on the CPU architecture). On Linux, this function is implemented using the pthreads APIs. For non-main threads, the queried thread info is stored in memory. The main thread does not have this information on hand, so it gets the stack memory range via the /proc/self/maps file (see glibc's pthread_get_attr_np.c). Fortunately (per discussions with the firefox devs in #jsapi) the base address only needs to be approximate. In reality, environment variables, args, and other things are stored in stack space between the end/beginning of the mapped stack memory and the 'top' of the stack space used by stack frames. When using glibc, we can get the top of this usable stack from __libc_stack_end, which is a void* set by glibc during program initialization, avoiding the need to access /proc. Non-main threads still get their stack-base through the usual pthreads APIs. Other libc implementations like musl will fall back to the standard UNIX-like implementation which calls pthread's pthread_attr_getstack() also from the main thread, which may imply /proc access and not work in restricted environments.

| | | | | | | | | | | | | | | | | | - `--enable-official-branding` implies `MC_OFFICIAL` (no need to specifically set it) - `--enable-official-vendor` can be used to set `MC_OFFICIAL` on builds without `--enable-official-branding` that should still be considered official release versions. - `MC_OFFICIAL` implies `--enable-release`, meaning `DEVELOPER_OPTIONS` isn't set - `MC_OFFICIAL` makes `nsXULAppInfo.getIsOfficial` return `true` - `MC_OFFICIAL` makes `AppConstants.MOZILLA_OFFICIAL` (for compatibility in extensions) and `AppConstants.MC_OFFICIAL` return `true` - Optional, for the time being: `MOZILLA_OFFICIAL` is still present in some places in case someone wants to build a Mozilla-alike official application and has the rights and necessary keys to use Mozilla-official third-party services. This must always be combined with `MC_OFFICIAL` to have a sane combination of defines. This may be removed in the future.
