Build system support for LTO
https://bugs.webkit.org/show_bug.cgi?id=187785
<rdar://problem/42353132>
Reviewed by Dan Bernstein.
.:
Add support for building WebKit with LTO (Link Time Optimization) on
macOS and iOS. Both variations are supported: "full" (which performs
all the optimizations it can regardless of the cost) and "thin" (which
sacrifices some optimizations in order to recover build time and
memory usage).
By default, LTO is disabled for Debug and Release builds, but is
enabled for Production builds. For Debug and Release builds, LTO is
controlled as follows:
- When using `make` from the command line, include
WK_LTO_MODE={none,thin,full}. For example, `make WK_LTO_MODE=full
release`. As when specifying debug/release, the LTO configuration
information is written to the WebKitBuild directory and is used as
the default on the next build if a new setting is not specified.
- When using `build-webkit`, include --lto-mode={none,thin,full} on
the command line. For example, `build-webkit --lto-mode=full ...`.
- When using Xcode, create a configuration file called
LocalOverrides.xcconfig at the root level of your WebKit checkout
directory. Include within it a line that says:
WK_LTO_MODE={none,thin,full}
For example:
WK_LTO_MODE=full
Note that LocalOverrides.xcconfig is included in the .gitignore file,
so you won't accidentally check your changes into source control.
Enabling LTO can greatly increase build times, especially when using
"full" LTO with 32GB or RAM or less. Following is a table of full
build times for a Release build on a fully decked-out 2017 iMac Pro:
LTO macOS iOS
----- ------- -------
None: 9m 11s 14m 11s
Thin: 11m 44s 17m 30s
Full: 21m 39s 28m 56s
Incremental times are affected even more greatly. The actual
optimization and compilation of LLVM bitcode is moved to the link
phase, meaning that the link phase, which previously took only
seconds, can now take many minutes. It's for this reason that LTO is
not enabled in Debug and Release builds, since incremental builds are
an integral part of those configurations. However, using the
mechanisms described above, developers can perform optional LTO builds
if needed to track down build or runtime issues in that configuration.
