30 In a simple two-stage bootstrap build, we build clang using the system compiler,
64 build using the compiler installed on the host, and a stage2 build is built
65 using the stage1 compiler. This nomenclature holds up to more stages too. In
74 The stage1 compiler is a host-only compiler with some options set. The stage1
75 compiler is a balance of optimization vs build time because it is a throwaway.
76 The stage2 compiler is the fully optimized compiler intended to ship to users.
80 You can build an Apple Clang compiler using the following commands:
87 This CMake invocation configures the stage1 host compiler, and sets
92 compiler and required tools, then configures and builds the stage2 compiler
106 At a high level, the way PGO works is that you build an instrumented compiler,
107 then you run the instrumented compiler against sample source files. While the
108 instrumented compiler runs it will output a bunch of files containing
123 and you *must* have compiler-rt in your build tree.
136 optimized compiler.
140 stage2. Both of the stage2 builds are built using the stage1 compiler.
145 Builds a stage1 x86 compiler, runtime, and required tools (llvm-config,
146 llvm-profdata) then uses that compiler to build an instrumented stage2 compiler.
149 Depends on "stage2-instrumented" and will use the instrumented compiler to
154 compiler with the stage2 profdata to build a PGO-optimized compiler.
157 Depends on stage2 and runs check-llvm using the stage2 compiler.
160 Depends on stage2 and runs check-clang using the stage2 compiler.
163 Depends on stage2 and runs check-all using the stage2 compiler.
166 Depends on stage2 and runs the test-suite using the stage3 compiler (requires
175 Historically one of the tests to verify that a compiler was deterministic would
177 and build a compiler (stage1), then use that compiler to rebuild the sources
178 (stage2), then you use that compiler to rebuild the sources a third time
180 this, you have a stage2 and stage3 compiler that should be bit-for-bit
