* IC: renamed to_packed_ast module to ic module * IC: don't store the --forceBuild flag, makes it easier to test * IC: enable hello world test * Codegen: refactorings for IC; changed the name mangling algorithm * fixed the HCR regressions * life is too short for HCR * tconvexhull is now allowed to use deepCopy * IC exposed a stdlib bug, required a refactoring * codegen: code cleanups * IC: even if a module is outdated, its dependencies might come from disk * IC: progress * IC: better name mangling, module IDs are not stable * IC: another refactoring helping with --ic:on --gc:arc * disable arraymancer on Windows for the time being * disable arraymancer altogether * IC: make basic test work with 'nim cpp' * IC: progress on --ic:on --gc:arc * wip; name mangling for type info
