Shared libraries are not supported. - 2. The output format from this bfd is not usable by native tools. - - The primary motivation for writing this bfd was to allow use of - gdb and gcc for host based debugging and not to mimic the hp-ux tools - in every detail. This leads to a significant simplification of the - code and a leap in performance. The decision to not output hp native - compatible objects was further strengthened by the fact that the richness - of the gcc compiled objects could not be represented without loss of - information. For example, while the hp format supports the concept of - secondary symbols, it does not support indirect symbols. Another - reason is to maintain backwards compatibility with older implementations - of gcc on hpux which used 'hpxt' to translate .a and .o files into a - format which could be readily understood by the gnu linker and gdb. - This allows reading hp secondary symbols and converting them into - indirect symbols but the reverse it not always possible. - - Another example of differences is that the hp format stores symbol offsets - in the object code while the gnu utilities use a field in the - relocation record for this. To support the hp native format, the object - code would need to be patched with the offsets when producing .o files. - - The basic technique taken in this implementation is to #include the code - from aoutx.h and aout-target.h with appropriate #defines to override - code where a unique implementation is needed: - - { - #define a bunch of stuff - #include <aoutx.h> - - implement a bunch of functions - - #include "aout-target.h" - } - - The hp symbol table is a bit different than other a.out targets. Instead - of having an array of nlist items and an array of strings, hp's format - has them mixed together in one structure. In addition, the strings are - not null terminated. It looks something like this: - - nlist element 1 - string1 - nlist element 2 - string2 - ... - - The whole symbol table is read as one chunk and then we march thru it - and convert it to canonical form. As we march thru the table, we copy - the nlist data into the internal form and we compact the strings and null - terminate them, using storage from the already allocated symbol table: - - string1 - null - string2 - null - */ - -/* @@ Is this really so different from normal a.out that it needs to include - aoutx.h?
