Reduce the stack usage by replacing the mOCT6100_RETRIEVE_NLP_CONF_DWORD and mOCT6100_SAVE_NLP_CONF_DWORD macros with functions. Some compilers do a better job of optimizing the local variables declared in those macros than others. For example, with gcc 4.3.0, running ]# make stackcheck | grep Oct6100 | head -n 20 | sed -e 's/^0\S* //g' | uniq Before: Oct6100ApiWriteVqeNlpMemory [wct4xxp]: 1112 Oct6100ApiInvalidateChanPlayoutStructs [wct4xxp]:520 Oct6100ApiSetChannelLevelControl [wct4xxp]: 392 Oct6100ApiBridgeEventRemove [wct4xxp]: 344 Oct6100ApiDebugChannelOpen [wct4xxp]: 312 Oct6100ApiWriteVqeAfMemory [wct4xxp]: 296 Oct6100ApiSetChannelTailConfiguration [wct4xxp]:264 Oct6100ApiRandomMemoryWrite [wct4xxp]: 248 Oct6100ApiTransferToneEvents [wct4xxp]: 248 Oct6100ApiModifyChannelStructs [wct4xxp]: 232 After: Oct6100ApiBridgeEventRemove [wct4xxp]: 344 Oct6100ApiDebugChannelOpen [wct4xxp]: 312 Oct6100ApiRandomMemoryWrite [wct4xxp]: 248 Oct6100ApiTransferToneEvents [wct4xxp]: 248 Oct6100ApiInvalidateChanPlayoutStructs [wct4xxp]:248 Oct6100ApiModifyChannelStructs [wct4xxp]: 232 Oct6100ApiBridgeRemoveParticipantFromChannel [wct4xxp]:216 Oct6100ApiWriteVqeNlpMemory [wct4xxp]: 200 Oct6100ApiInitChannels [wct4xxp]: 168 Oct6100ApiProgramNLP [wct4xxp]: 168 Signed-off-by: Shaun Ruffell <sruffell@digium.com> git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@9751 a0bf4364-ded3-4de4-8d8a-66a801d63aff

Macros used to shell the user function calls. These macros are used to
|
|
assert that the user does not change any of the members of the function's
|
|
parameter structure, as required and indicated in the API specification.
|
|
Ofcourse, these macros make the code heavier and thus slower. That is why
|
|
there is a compile option for disabling the extra checking. These can be
|
|
very helpful tools in debugging.
