* module/language/ghil/compile-glil.scm (codegen): Record source location for offset 0 into a lambda, if we can. * module/language/scheme/compile-ghil.scm (translate-1) (define-scheme-translator): In the retrans procedures, propagate the location information from the enclosing expression if the subexpression has no location information. Gives source information to many more expressions. (location): Just propagate the source properties as they are, the glil->assembly compiler will interpret them. * module/language/glil.scm (<glil>): Change glil-source to take "props" and not "loc", as it's the source properties that we're interested in. * module/language/glil/compile-assembly.scm (limn-sources): New function, takes a list of addr-source property pairs and "compresses" them for serialization to disk. (glil->assembly): Limn the sources before writing them to disk. Avoid non-tail recursion when determining total byte length of code. * module/system/vm/program.scm (source:file, source:line, source:column): Update for new source representation. (program-source): Export. (write-program): Nicer pretty-printing of anonymous procedures. * libguile/backtrace.c (display_backtrace_get_file_line): Update for the new VM source representation. * libguile/programs.h: * libguile/programs.c (scm_program_sources): Update for the new serialized source representation, where the filename is not in the stream unless it changes. (scm_program_source): New exported function, looks up the source for a given ip offset. (scm_c_program_source): Update to return the last source information that was <= the given IP, because we only serialize source info when it changes.
