5f02b0335f syscall/ and related: Fix an error found in build testing. Inconsistent conditional compilation led to link errors in certain configurations. 2019-08-27 16:41:07 -06:00

3c30cf1f05 Squashed commit of the following:
task_spawn() and posix_spawn() are NuttX OS interfaces.  In PROTECTED and KERNEL build modes, then can be reached from applications only via a system call.  Currently, the number of parameters in a system call is limited to six; these spawn function have seven parameters.  Rather than extend the maximum number of parameters across all architectures, I opted instead to marshal the seven parameters into a structure.
     *

In order to support builtin in function in protected mode, a task_spawn() system call must be supported.  Unfortunately this is overly complex because there is a (soft) limit of 6 parameters in a system call; task_spawn has seven paramters.  This is a soft limit but still difficult to extend because it involves assembly language changes to numerous architectures.  Better to get more creative.

cf99fb40c9 This commit moves all of the libraries under a common directory called libs/. This most certainly break libcxx and uClibc++ for now.
Squashed commit of the following:

    libs/libxx:  Fix some confusing in naming.  If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected).
    libs/:  Fix paths in moved library directories.
    libs:  Brute force move of libc, libnx, and libxx to libs.  Cannot yet build it in that configuration.
