/* These routines are not yet called from BFD. They are called from
|
|
the MIPS symbol reading code in GDB. However, they are in the BFD
|
|
library because they will eventually be useful if and when BFD
|
|
supports reading or writing of MIPS symbol tables.
|
|
|
|
FLASH! FIXME! Unfortunately MIPS has these *%&%&$#^# copyrighted
|
|
include files defining the symbol format (which I've been politely
|
|
asking them to release for public use for about a year now). Since
|
|
this function can only compile if these include files are available,
|
|
the config files for MIPS-based hosts configure the Makefile so that
|
|
this file will be compiled only if on a MIPS-based host. FIXME!
|
|
|
|
The routines in this file convert the external representation of
|
|
ECOFF symbol tables to the internal (usual struct) representation.
|
|
On a machine with the same byte-order and the same basic type
|
|
sizes and alignments as a MIPS machine, this is a no-op.
|
|
If the symbol TEST is defined when this file is compiled, a comparison
|
|
is made to ensure that, in fact, the output is bit-for-bit the same as
|
|
the input. Of course, this symbol should only be defined when
|
|
deliberately testing the code on a machine with the proper byte sex
|
|
and such. */
