gcc also supports "bounded" - do you plan to somehow handle it? (https://gcc.gnu.org/onlinedocs/gcc/Developer-Options.html#Developer-Options), eg: parser.c:918:5:parse_statement  48      dynamic,bounded



================
Comment at: clang/test/CodeGen/stack-usage.c:7
+// RUN: FileCheck %s < %T/b.su
+// RUN: %clang_cc1 -triple arm-unknown -fstack-usage -fstack-usage=%T/c.su -emit-obj %s -o %T/c.o
+// RUN: FileCheck %s < %T/c.su
----------------
-fstack-usage=file.su is Clang only, right? Tried with GCC, gcc error: unrecognized command-line option ‘-fstack-usage=xxx’,

Do we need to also specify extra -fstack-usage if -fstack-usage=file.su  is used? Seems quite redudant and -fstack-usage=file.su alone should be enough.
