Bug ID: 49016
Summary: 16-byte alignment adds significant bloat to the object
file
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: AArch64
Assignee: unassignedb...@nondot.org
Reporter: wxbl...@gmail.com

Created attachment 24477
--> https://bugs.llvm.org/attachment.cgi?id=24477&action=edit
Assembly files (to reproduce the problem) and their corresponding object files
problem.S and okay.S are identical except for alignment; the former uses
16-byte alignment while the latter uses 8-byte. When compiled, problem.o is
~65KB and okay.o is ~1KB.
In both cases, the following command-line was used:
clang -o <file>.o -c <file>.S --target=aarch64-none-eabi
