description="""
Compares code sizes of "new" files, taking "old" files as a reference.
Environment variables:
SWIFT_NEW_BUILDDIR The new build-dir
E.g. .../swiftnew/build/Ninja-ReleaseAssert+stdlib-Release/swift-macosx-x86_64
SWIFT_OLD_BUILDDIR The old build-dir
E.g. .../swiftold/build/Ninja-ReleaseAssert+stdlib-Release/swift-macosx-x86_64
How to specify files:
1) No files:
Compares codesize of the Benchmark_* executables and the swiftCore dylib in
the new and old build-dirs.
Example:
cmpcodesize
2) One or more paths relative to the build-dirs (can be a pattern):
Compares the files in the new and old build-dirs.
Aliases:
O => bin/Benchmark_O
Ounchecked => bin/Benchmark_Ounchecked
Onone => bin/Benchmark_Onone
dylib => lib/swift/macosx/x86_64/libswiftCore.dylib
Examples:
cmpcodesize Onone
cmpcodesize benchmark/PerfTestSuite/O/*.o
3) Two files:
Compares these two files (the first is the old file).
Example:
cmpcodesize test.o newversion.o
4) Two lists of files, separated by '--':
Compares a set of files.
Example:
cmpcodesize olddir/*.o -- newdir/*.o
5) One file (only available with the -l option):
Lists function sizes for that file
Example:
cmpcodesize -l test.o""")
