This CL fixes a typo in writeFakeNinjaFile to correctly write a fake out/soong/build.ninja and its depfile. It also modifies bootstrap phase to *not* run the main soong build phase (which takes more than a minute) if GENERATE_BAZEL_FILES=1. This change has the side effect that `GENERATE_BAZEL_FILES=1 m nothing` no longer generates the real build.ninja, which is fine because one shouldn't be using GENERATE_BAZEL_FILES=1 for that anyway (or, use USE_BAZEL_ANALYSIS=1). This change has no effect on mixed builds. Time on a change to Soong or any Android.bp files: Before: bp2build_workspace_marker (~20 seconds) + build.ninja (1 min) After: bp2build_workspace_marker (~20 seconds) Time on the second of two consecutive `b build //bionic/...`: 2.070s Test: TH Test: Soong integration tests Change-Id: I43720641815994caba97b8d165d7c3fc254cbd06 |
