Despite our attempt (build-docs.sh) to build the documentation with SVG, it still uses PNG https://llvm.org/doxygen/classllvm_1_1StringRef.html, and that renders terribly on any high dpi display. SVG leads to smasller installation and works fine on all browser (that has been true for _a while_ https://caniuse.com/svg), so this patch just unconditionally build all dot graphs as SVG in all subprojects and remove the option.
BOLT Documentation ==================== The BOLT documentation is written using the Sphinx documentation generator. It is currently tested with Sphinx 1.1.3. To build the documents into html configure BOLT with the following cmake options: * -DLLVM_ENABLE_SPHINX=ON * -DBOLT_INCLUDE_DOCS=ON After configuring BOLT with these options the make rule `docs-bolt-html` should be available.
