Subject: [Bug target/32838] New: gcc generates incorrect trampoline code in thumb mode
Date: Fri, 20 Jul 2007 11:52:00 -0000 [thread overview]
Message-ID: <bug-32838-14845@http.gcc.gnu.org/bugzilla/> (raw)
When using nested functions, the trampoline code will destroy register 9 while
loading the static chain. This is even noted in gcc/config/arm/arm.h:
XXX FIXME: When the trampoline returns, r8 will be clobbered.
(it will be r9 and not r8...).
The attached patch avoids clobbering r9.
