| 619 done in the serial driver. Added cyg_hal_is_break() and | |
| 620 cyg_hal_user_break() to detect and provoke ^C processing. These | |
| 621 are used by the serial driver and will one day interact with the | |
| 622 BSP/Cygmon/GDB stubs to do the right thing. | |

| 655 mangled by C++. This is intended to make support for interrupt | |
| 656 handling in non-kernel configurations easier. | |
| 657 Added some code to initialize DRAM in ROM-only configurations. | |

| 663 passing a third, hidden argument to hal_ctrlc_isr() which is a | |
| 664 pointer to the saved CPU state. | |
| 665 | |
| 666 * src/vectors.S: | |
| 667 Added support for 66MHz part (untested). | |
| 668 Added support for SIGINT-causing magic breakpoint to allow | |
| 669 continuation after ^C. This also relies on CYGMON changes. | |

| 737 RAM startup (CYG_HAL_STARTUP_RAM) so that minimal sim testing | |
| 738 works. Note: this is an instance where two definitions (of | |

| 903 Made vectors.o dependent on the various files that can contain | |
| 904 makefile variables or rules. This is needed after changes to | |
| 905 pkgconf.tcl for PRs 17195 and 17286. | |

| 918 into one that can be used in the HAL. Added calls to it in | |

| 924 Added missing descriptions (PR 17184) | |
| 925 | |
| 926 * src/vectors.S: | |
| 927 <pkgconf/kernel.h> was being included without properly checking | |
| 928 that the kernel package was enabled. | |
| 929 | |
| 930 * src/hal_misc.c (exception_handler): | |
| 931 Sort out exception handling options (PR 16953) | |
| 932 | |

| 954 Tue Sep 1 19:26:45 1998 Hugo Tyson <hmt@cygnus.co.uk> | |
| 955 | |
| 956 * src/hal_misc.c: | |
| 957 Use CYGDBG_INFRA_DIAG_USE_DEVICE (from infra.h) instead of | |
| 958 CYG_DIAG_USE_DEVICE (badly named, from kernel.h). | |
| 959 | |
| 960 1998-09-01 Nick Garnett <nickg@cygnus.co.uk> | |

| 971 | |
| 972 * src/hal_misc.c: | |
| 973 Rename __main() to cyg_hal_invoke_constructors() to prevent the | |
| 974 implied link with things called, or related to main(). Remove static | |
| 975 initialised variable as we can now guarantee it is only called | |
| 976 once. | |
| 977 | |
| 978 * src/vectors.S: | |
| 979 Instead of calling main(), call cyg_start() which lives in the infra | |
| 980 package. | |
| 981 Explicitly invoke constructors as it isn't done magically for us | |
| 982 any more, now that main() is no longer used. | |
| 983 | |
| 984 | |
| 985 1998-08-25 Nick Garnett <nickg@cygnus.co.uk> | |
| 986 | |
| 987 * src/vectors.S: | |
| 988 Now pass pointer to saved registers as third argument to | |
| 989 interrupt_end(). | |
| 990 | |
| 991 * include/hal_arch.h: | |
| 992 Added macros to support GDB. | |
| 993 | |
| 994 Tue Aug 25 02:33:59 1998 Jonathan Larmour <jlarmour@cygnus.co.uk> | |
| 995 | |
| 996 * include/mips_stub.h, src/hal_misc.c: | |
| 997 Add void to prototypes and typedefs that want it to silence warnings | |
| 998 | |
| 999 1998-08-21 Nick Garnett <nickg@cygnus.co.uk> | |
| 1000 | |
| 1001 * include/hal_cache.h: | |
| 1002 Now includes cyg_type.h rather than ktypes.h. | |
| 1003 | |
| 1004 1998-08-18 Nick Garnett <nickg@cygnus.co.uk> | |
| 1005 | |
| 1006 * src/context.S: | |
| 1007 * include/hal_arch.h: | |
| 1008 * include/hal_io.h: | |
| 1009 * include/hal_intr.h: | |
| 1010 Now uses cyg_type.h rather than ktypes.h. | |
| 1011 | |
| 1012 * src/hal_misc.c: | |
| 1013 * src/vectors.S: | |
| 1014 Now uses hal.h rather than kernel.h. | |
| 1015 | |
| 1016 1998-07-23 Nick Garnett <nickg@cygnus.co.uk> | |
| 1017 | |
| 1018 * include/hal_intr.h: Fixed some issues raised bt code review. | |
| 1019 | |
| 1020 * src/context.S: | |
| 1021 * include/hal_arch.h: Fixed some typos raised by code review. | |
| 1022 | |
| 1023 * include/hal_intr.h (HAL_INTERRUPT_MASK): | |
| 1024 * src/vectors.S (hal_interrupt_level): Added hal_interrupt_level | |
| 1025 to allow for interaction between HAL_INTERRUPT_UNMASK() and | |
| 1026 HAL_INTERRUPT_SET_LEVEL(). | |
