Some of the tasks + performed by PXDB are: + + o Remove duplicate global type and variable information + from the GNTT, + + o Append the GNTT onto the end of the LNTT and place both + back in the LNTT section, + + o Build quick look-up tables (description follows) for + files, procedures, modules, and paragraphs (for Cobol), + placing these in the GNTT section, + + o Reconstruct the header appearing in the header section + to access this information. + + The "quick look-up" tables are in the $GNTT$ sub-space, in + the following order: + + Procedures -sorted by address + Source files -sorted by address (of the + generated code from routines) + Modules -sorted by address + Classes -<unsorted?> + Address Alias -sorted by index <?> + Object IDs -sorted by object identifier + + Most quick entries have (0-based) indices into the LNTT tables to + the full entries for the item it describes. + + The post-PXDB header is in the $HEADER$ sub-space. Alas, it + occurs in different forms, depending on the optimization level + in the compilation step and whether PXDB was run or not. The + worst part is the forms aren't self-describing, so we'll have + to grovel in the bits to figure out what kind we're looking at + (see hp_get_header in hp-psymtab-read.c). */ + +/* PXDB versions. */ + #define PXDB_VERSION_CPLUSPLUS 1 #define PXDB_VERSION_7_4 2 #define PXDB_VERSION_CPP_30 3 @@ -1605,118 +1613,106 @@ typedef struct { #define PXDB_VERSION_2_1 1 /* Header version for the case that there is no DOC info - * but the executable has been processed by pxdb (the easy - * case, from "cc -g"). - */ -typedef struct PXDB_struct { - int pd_entries;
