It's not necessary to do rounding for alloca operations when the requested

alignment is equal to the stack alignment.

+# Synopsis: This shell script is a replacement for the old "gccas" tool that
+#           existed in LLVM versions before 2.0. The functionality of gccas has
+#           now been moved to opt and llvm-as. This shell script provides 
+#           backwards compatibility so build environments invoking gccas can
+#           still get the net effect of llvm-as/opt by running gccas.
+#
+# Syntax:   gccas OPTIONS... [asm file]
