Modified files:
lib/libc_r Makefile
lib/libc_r/uthread pthread_private.h uthread_create.c
uthread_gc.c uthread_init.c
Log:
Use growable stacks for thread stacks that are the default stack size.
Cache discarded default thread stacks for use in subsequent thread creations.
Create a red zone at the end of each stack (including the initial thread
stack), with the hope of causing a segfault if a stack overflows.
To activate these modifications, add -D_PTHREAD_GSTACK to CFLAGS in
src/lib/libc_r/Makefile. Since the modifications depend on the VM_STACK
kernel option, I'm not sure how to safely use growable stacks by default.
Testing, as well as algorithmic and stylistic comments are welcome.
