I'm a dabbler, but I've noticed that on solaris/amd64 first 17 (high)
bits of a stack pointer are 1's. Always.
So we can use them as on linux (instead of 0's). Does it make sense?

You can use this function, declared in js

I'm building Firefox for a solaris-based system on amd64 processor, e.
i. Firefox is to be an 64-bit application.
I've found that during the build xpcshell crashes [1]:

Some idea:
BUILD_JSVAL(JSValueTag tag, uint64_t payload)
{
jsval_layout l;
+#if SOLARIS_STACK_LAYOUT
+payload &= JSVAL_PAYLOAD_MASK;
+#endif
l.asBits = (((uint64_t)(uint32_t)tag) << JSVAL_TAG_SHIFT) |
payload;
return l;
}

Hm... It looks like JSVAL_PAYLOAD_MASK is to cut off JSValueTag in
typedef union jsval_layout from payload.
It looks like an optimization on amd64 agains i386, but this does not
work on solaris.
Someone put JSValueTag into pointer instead of a field of a struct.
