Subject: [PATCH] arm64: Handle sp, lr, fp as DwReg in CfiExpr
|
|
|
|
When copy_convert_CfiExpr_tree sees a DwReg on arm64 we simply call
|
|
I_die_here; This causes an issue in the case we really do have to handle
|
|
that case (see https://bugzilla.redhat.com/show_bug.cgi?id=1923493).
|
|
|
|
Handle the stack pointer (sp), link register (x30) and frame pointer
|
|
(x29),
|
|
which we already keep in D3UnwindRegs, like we do for other
|
|
architectures
|
|
in evalCfiExpr and copy_convert_CfiExpr_tree.

+* ==================== FIXED BUGS ====================
|
|
+
|
|
+The following bugs have been fixed or resolved. Note that "n-i-bz"
|
|
+stands for "not in bugzilla" -- that is, a bug that was reported to us
|
|
+but never got a bugzilla entry. We encourage you to file bugs in
|
|
+bugzilla (https://bugs.kde.org/enter_bug.cgi?product=valgrind) rather
|
|
+than mailing the developers (or mailing lists) directly -- bugs that
|
|
+are not entered into bugzilla tend to get forgotten about or ignored.
|
|
