new 6906853 Improve proxy/stub parameter passing for variadic OS
interfaces.
6906853 is described below
commit 6906853f8e2cb12407dfc73562ad2b3cdb0b49b1
Author: Gregory Nutt <gn...@nuttx.org>
AuthorDate: Tue May 5 15:02:07 2020 -0600
Improve proxy/stub parameter passing for variadic OS interfaces.
In the past a very low effort interface was used:
- All parmeters were treated as though they were type uinptr_t, and
- The maximum number of parmeters (6) was passed in all cases.
The first is potentially wrong and the second is very inefficient. This
commit improves this by:
- Making tools/mksyscall.c more intelligent, and
- Extending the syntax for variadic functions.
For example, in syscall.cvs, the open() API was represened like this:
"open","fcntl.h","","int","const char*","int","..."
In reality, open may take only a single optional argument of type mode_t
which is not the same size as uintptr_t. And there is not reason to pass 6
parameters in that case.
And this has been extended to:
"open","fcntl.h","","int","const char*","int","...","mode_t"
The existence of the "mode_t" tells tools/mksyscall that there is at most
one optional parameter and, if present, it is of type mode_t.
