On x86-64, PLT optimization does not require the binary to be linked with -znow because indirect calls through GOT work correctly with lazy binding. At runtime, the dynamic linker's resolver will populate the GOT entry on the first call, just like with a regular PLT call. This change removes the -znow requirement specifically for x86-64 while keeping it for other architectures. I haven't checked RISV-V, but it's still necessary on AArch64.
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.
