# PA Changes:
# Strip binaries to optimize size (thanks Ju Hyung Park)
# Restore symlinks to reduce I/O (thanks Ju Hyung Park)
# Make LLD binaries executable to fix build errors
# Symlink identical files instead of duplicating

# Strip binaries:
find . -type f -exec file {} \; \
    | grep "x86" \
    | grep "not strip" \
    | grep -v "relocatable" \
        | tr ':' ' ' | awk '{print $1}' | while read file; do
            strip $file
done

find . -type f -exec file {} \; \
    | grep "ARM" \
    | grep "aarch64" \
    | grep "not strip" \
    | grep -v "relocatable" \
        | tr ':' ' ' | awk '{print $1}' | while read file; do aarch64-elf-strip $file
done

find . -type f -exec file {} \; \
    | grep "ARM" \
    | grep "32.bit" \
    | grep "not strip" \
    | grep -v "relocatable" \
        | tr ':' ' ' | awk '{print $1}' | while read file; do arm-eabi-strip $file
done

# Restore symlinks:
find * -type f -size +1M -exec xxhsum {} + > list
awk '{print $1}' list | uniq -c | sort -g
rm list

# Make LLD binaries executable:
chmod a+x compiler/bin/ld*

# Capture major version number for symlinks to clang-$MAJOR_VERSION
MAJOR_VERSION=$(ls compiler/lib/clang | cut -d. -f1)

# Symlink identical files instead of duplicating
