History

Gregory Nutt 641a98a434 arch/: The saved return register state is available on the user stack. Thic commit reorders some logic so that certain, critical registers are preserved in the TCB. This does not make the logic 100% secure, but does prevent some obvious things. sched/signal/sig_delivery: Add a flag to the TCB to indicate that we are in a signal handler. Use this flag to assure that a there a never attempts to nest signal handling operations on a thread. This was guaranteed before but when locking of pre-emption during signal delivering was eliminated in a previous commit, there was a remote possibility of an attempt to do nested signal handling. This flag assures that there is only one signal handled at a time.		2019-02-03 15:29:47 -06:00

Makefile	Build system: Remove fixed lib/ subdirectory and its content. Replace with new directory called staging/ that is created dynamically when building and removed when 'make clean' is done. This both improves the name and eliminates a garbage directory from the repository.	2018-05-29 11:36:21 -06:00

README.txt

This directory provides a build area for all Renesas and legacy Hitachi
architectures.  The 'common' subdirectory contains source files shared by
all Renesas architectures; Source files unique to a specific Renesas chip
architecture are contained in a subdirectory named after the chip.  At
configuration time, additional directories will be linked here:  'board'
will be a link to the configs/*/src directory; 'chip' will be a link to
the SH chip sub-directory.
