* A patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1998-08-215-75/+295
| | | | | | | | | | | | | | | | | | | | | | | | | | Here is another patch to hopefully enhance rtems' configuration. Motivation: Try to support other c-compilers besides gcc (I tried to build rtems under Solaris using sun's WSPro c-compiler). Here is a couple of small patches concerning the host compiler configuration, which fix/work-around the worst problems when using sun's WSPro c-compiler. Changes: * Replaced make/compilers/gcc.cfg with make/compilers/gcc.cfg.in, ie. gcc.cfg is generated by configure now. * Removed a line containing a hard-coded "gcc" from gcc.cfg (BUG-fix). * Add -g to host compiler flags only if configure reported -g to work * Add -Wall to host compiler flags only if configure reported that the host compiler is gcc (WSPro's cc chokes on -Wall). * Some modifications to make/Makefile.in * Adapted make/custom/default.cfg to the new location of gcc.cfg BTW, gcc.cfg/gcc.cfg.in seems to be full of unused code (DEBUG-VARIANTS etc.) which deserves to be cleaned up, IMO. IMO, a similar patch should be applied to gcc-target-default.cfg

| | | | | | | | | | Here is a patch that enables to catch exception and get message before crashing RTEMS :) It should be generic to any Intel port although enabled only for pc386 BSP... [Joel] I fixed the bug I introduced in irq_asm.s...

Yes, there's a bug there. I thought that Joel had patched this already, but here's a patch to fix this. This patch also addresses a concern that many others have raised regarding enabling and disabling of transmitter interrupts. First, here's the example I've been using of a simple UART-style interrupt-driven driver: =============================================================== void device_write_routine (int minor, char *buf, int count) { UART->control_register &= ~UART_TRANSMITTER_READY; UART->output_register = *buf; UART->control_register |= UART_TRANSMIT_INTERRUPT_ENABLE; } void device_transmit_interrupt_routine (int vector) { UART->control_register &= ~UART_TRANSMIT_INTERRUPT_ENABLE; rtems_termios_dequeue_characters (device_ttyp, 1); } ============================================================== Several people have expressed their concern about the disable/enable of transmitter interrupts for every character. On some machines this disable/enable is an expensive operation. With the attached patch applied you can write the two routines as: ============================================================== void device_write_routine (int minor, char *buf, int count) { code_to_clear_transmitter_ready_status (); if (device_ttyp->rawOutBufState == rob_idle) code_to_enable_transmitter_interrupts (); code_to_send_one_character_to_transmitter (*buf); } void device_transmit_interrupt_routine (int vector) { rtems_termios_dequeue_characters (device_ttyp, 1); if (device_ttyp->rawOutBufState == rob_idle) code_to_disable_transmitter_interrupts (); } ===============================================================
