The latest several commits break JaegerMonkey on Solaris x86 with Sun Studio 12.
The patch include the following fixes.
1. Disable YARR_CALL for sunstudio.
2. Modify TrampolineSUNWX86.s according the latest changes.
3. Fix a fast call related problem in js_InternalThrow.
4. Fix a build error on sunstudio.

Is it possible to change the forceReturn trampoline instead of this hack?

forceReturn is used by both js_InternalThrow and some fast calls. Another solution is to add a forceReturnFast similar as forceReturn.

This patch didn't do hack things. But there are more changes.

Since the patch for bug 587833 lunched, we need to modify solaris trampolines too.

Patch 4

Leon, the JM tree is now for debugging/testing only. The patch that caused this problem hasn't landed on TM yet.

I'll make sure to integrate your fix into the final check-in. Thanks!

Thank you for noticing. I'll also monitor the TM tree.
