Not this case, but how is one supposed to use this directly from the
compiler/assembler without linker mapfiles? Might be interesting to add
support to GCC in the future.
A couple of other questions:
* You're currently using v1 mapfile syntax in the LLM excerpt. I
suppose this is because this case requests patch/micro binding, but it
should state the v2 syntax, too.
* In the example on p.76 of the LLM, what happens if the machine
provides e.g. both MMX and SSE. Which instance of foo will be used in
this case? I suppose there is a similar ordering like the one
described on p.380 (descending order of capability values), but is
this supposed to be documented or implementation defined?
* Does LD_CAP_FILES match the file names of shared objects, or their
SONAMEs, exact or substring match?
Thanks.
