6df4bd8f8c Fix a few more warnings
Some are important, e.g. the seemingly harmless braces around if with dprintf,
since that dprintf is defined as empty, will screw things up and grab the next
line

a1b50051ed mcexec: always compile debug statements
This helps catching errors like accessing a field that no longer exists
in a debug print that wasn't compiled...

aaa246f86f mcexec: change debug printf macros to be more tolerant to trivial format
Enabling DEBUG fails to compile. It'd be easy to fix the dprintf to dprint
but this is just as generic and we can now use dprintf everywhere

4f2c1e07c1 Add ARCH variable to Makefiles
In some Makefiles the ARCH variable was not set, although it was used.
In executer/user/Makefile.in it was used before it was set.

b894619d1b Speed up parallel builds
- make should be $(MAKE)
 - add + in front of rules spawning long-lasted make process in a
subshell. (This would not be needed with $(MAKE) -C .. target, but our
makefiles do not handle that because they use $(PWD))
 - split the main 'all' rule as all 4 targets are independant
 - fix dependencies where appropriate for parallelism

Extra, not speed-related changes:
 - remove some double-colon for targets as they do not need it

This cuts build time from 5s to 1.5s on a laptop with -j4, and more
importantly from 85s to 35s on a KNL node.
As a bonus, the fixed dependencies removes the need to clean before
rebuilding all the time. Probably.

<premap_size> of stack is pre-mapped on creating a process.
And its max size of stack is set to <max>.
This replaces MCKERNEL_RLIMIT_STACK=<premap_size>,<max>.

38961fca78 Revert "do_fork(): RLIMIT_NPROC check"
This reverts commit 035e7913d8.
2017-07-13 04:13:41 +09:00
035e7913d8 do_fork(): RLIMIT_NPROC check
1. mcexec sets RLIMIT_NPROC to the number of mcexec threads.
2. do_fork() gets the current number of threads by calling rusage function.
3. do_fork() returns -EAGAIN when the limit is exceeded.
