* Build msp430-specific libnosysDJ Delorie2015-12-171-0/+4
| | | | | | | | | | The MSP430 debuggers support I/O on hardware through CIO, so we can use a CIO-enabled library as the "nosys" library (in addition to the libsim library, which talks to our simulator) * configure.in: Don't build default libnosys for msp430 * configure: Regenerate. * msp430/Makefile: Rename libcio to libnosys.
* Update CIO hooks to be more flexible.DJ Delorie2015-12-171-0/+5
| | | | | | | Replace the one hook we had with two to avoid underscore issues. * msp430/cio.c: Remove, replace with... * msp430/cio.S: New, this.
* rl78: Don't output CR when LF is encountered in write().Kevin Buettner2015-12-161-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The file libgloss/rl78/write.c currently contains code which outputs \r when \n is seen. The code will then output the \n as well. This patch removes the bit of code that tests for \n and then outputs \r. I made this change to fix some failures in gdb.base/call-ar-st.exp. In that test, I see two carriage returns followed by a newline. One CR is output by the libgloss code. The other is output by the terminal driver. The total list of failures fixed (using the default rl78 multilib) are: FAIL: gdb.base/call-ar-st.exp: print print_double_array(double_array) (timeout) FAIL: gdb.base/call-ar-st.exp: print print_char_array(char_array) (timeout) FAIL: gdb.base/call-ar-st.exp: continue to tbreak2 (timeout) FAIL: gdb.base/call-ar-st.exp: continuing to tbreak3 (timeout) FAIL: gdb.base/call-ar-st.exp: print print_double_array(array_d) (timeout) FAIL: gdb.base/call-ar-st.exp: continuing to tbreak4 (timeout) FAIL: gdb.base/call-ar-st.exp: print sum_array_print(10, *list1, *list2, *list3, *list4) (timeout) FAIL: gdb.base/call-ar-st.exp: print print_small_structs (timeout) FAIL: gdb.base/call-ar-st.exp: print print_ten_doubles(123.456, 123.456, -0.12, -1.23, 343434.8, 89.098, 3.14, -5678.12345, -0.11111111, 216.97065) (timeout) FAIL: gdb.base/call-ar-st.exp: print print_small_structs from print_long_arg_list (timeout) FAIL: gdb.base/call-ar-st.exp: print print_struct_rep(*struct1, *struct2, *struct3) (timeout) FAIL: gdb.base/dprintf.exp: call: printf: 1st dprintf (timeout) FAIL: gdb.base/dprintf.exp: call: printf: 2nd dprintf (timeout) FAIL: gdb.base/interrupt.exp: process is alive (the program exited) There are no regressions. libgloss/ChangeLog: * rl78/write.c (_write): Don't output CR when LF is encountered.

| | | | | | | Wrong paranthesis and an incorrect symbol name are fixed. * or1k/boards/optimsoc.S: Fix symbol name * or1k/crt0.S: Remove paranthesis
* or1k: Allow exception nestingJeff Johnston2015-08-071-0/+6
| | | | | | | | | | | | | | | | | | | Allow exceptions to be nested, which is especially useful with urgent interrupts while processing an exception. The implementation counts up the nesting level with each call to an exception. In the outer exception (level 1), the exception stack is started. All nested exceptions just reserve the redzone (scratch memory that may be used by compiler) and exception context on the stack, but then process on the same scratch. Restriction: Impure pointers are shared among all exceptions. This may be solved by creating an impure data structure in the stack frame with each nested exception. * or1k/crt0.S: Add exception nesting * or1k/exceptions-asm.S: ditto * or1k/util.c: ditto

* or1k: Add missing initialization of impure ptrJeff Johnston2015-05-271-0/+4
| | | | * or1k/impure.c: Fix initialization of impure ptr
* or1k: set heap start for optimsoc-gzllJeff Johnston2015-05-271-0/+4
| | | | | | | | | | | | | | | | | | | - With the gzll kernel we have two different loading options: - If the image is loaded to the global memory, the bootstrapping loads the kernel to local memory. Applications are loaded on demand. The heap then starts right after bss. - If the image is pre-loaded to the local memory it includes the application binaries right after bss. The heap then starts after the application objects. - We can check if this is a gzll kernel as it has the string "gzll" at 0x2000. At 0x200c we then find the end of the application objects in the image. If there is no global memory we set _or1k_heap_start to this value. * or1k/boards/optimsoc.S: Heap for gzll kernel
* or1k: Make heap start configurableJeff Johnston2015-05-271-0/+4
| | | | | | | | | - Previously the heap started right after the bss section. This can now be configured by changing the _or1k_heap_start symbol that defaults to the old value (&end). In board_init_early, we can now set this to another value. * or1k/sbrk.c: Allow for different heap start
* or1k: UART also accept timeout interruptJeff Johnston2015-05-271-0/+4
| | | | | | | - The UART interrupt only handled receiver FIFO full interrupts, but we also want to handle timeout interrupts. * or1k/or1k_uart.c: Fix interrupts
* Bug fix in timer for or1kJeff Johnston2015-05-271-0/+4
| | | | | | - Properly set the interrupt pending flag in the timer mode register. * or1k/timer.c: Properly set interrupt flags
* Store entire context for or1kJeff Johnston2015-05-271-0/+4
| | | | | | | | - Store the exception program counter (from EPCR) and exception status register (from ESR) also during the exception. A runtime system may replace them thereby to implement a thread switch. * or1k/exception-asm.S: Store missing state
* Fix exception stack frame for or1kJeff Johnston2015-05-271-0/+5
| | | | | | | | | - We do not need a red zone here, as we do not operate on the current stack, but always use the clear exception stack. Also reserve two extra words for the context to store EPCR and ESR. * or1k/crt0.S: Fix exception stack frame * or1k/exception-asm.S: ditto
* Fix interrupt handling for or1k.Jeff Johnston2015-05-271-0/+4
| | | | | | | | | | | | - During interrupt handling the PICSR, table pointers and current interrupt line have been saved in incorrect registers and/or stored on the stack. - Save the pointer in r16/r18, PICSR in r20 and the current interrupt line in r22. Those are callee-saved registers, so that the register values will be preserved. * or1k/interruts-asm.S: Change registers to callee-saved.
* Add a check that the data area does not overrun the stack.Nick Clifton2015-05-271-0/+11
| | | | | | | | | | | * msp430/msp430-sim.ld (.stack): Add an assertion to make sure that the data area does not overrun the stack. PROVIDE a new symbol __stack_size to allow the user to set the limit. * msp430/msp430xl-sim.ld (.stack): Likewise. * rl78/rl78-sim.ld (.stack): Likewise. * rl78/rl78.ld (.stack): Likewise. * rx/rx-sim.ld (.stack): Likewise. * rx/rx.ld (.stack): Likewise.

* libgloss: mcore: add custom syscall headerMike Frysinger2015-04-231-0/+4

* libgloss: arm: fix copy & paste in syscall.hMike Frysinger2015-04-231-0/+4
| | | | | | This header was clearly copied from the common syscall.h and customized, but the header comment is no longer accurate -- this isn't the general file anymore.
