The gdb.base/remote test fails for 68HC11/68HC12: - The gdb.base/remote.c defines a data table that is too large to link for 68HC11 targets (it requires 48K of data). - For HC11/HC12, the data section is installed by the crt0. The data section has its image in ROM and it is copied to RAM by the startup code. With a 48K data table, it requires 96K of memory (48K rom, 48K ram). After the load, the data table is not initialized. It is initialized when we reached the 'main'. The following patch improves the gdb.base/remote test: - The remote.c data table is reduced to 1K for 68HC11 (only), and the test verifies only the 1K load for 68HC11 (other platforms still use 48K). - It checks for a new 'gdb,noloaddata' configuration variable and runs to the main before verifying the load. Can you approve this patch? Thanks, Stephane 2001-05-20 Stephane Carrez * gdb.base/remote.c (RANDOM_DATA_SIZE): New define, defaults to 48K and defined to 1K for m68hc11. (random_data): Reduce table to 1K for embedded platforms (68hc11). * gdb.base/remote.exp (remote_data_size): New variable to tell the size of the data table; don't test past this size; check for gdb,noloaddata and run to the main if it is set (data section installed by crt0).

The test gdb.base/callfwmall.exp checks for the GDB ability to 'call/print' a function of the inferior. Several print commands require the program to have 'malloc' so that GDB allocates a string for input parameters. The 'callfwmall.c' file does not have any reference to malloc, which means that the final executable may not have it. This is my case for HC11. This means that the test fails with: (gdb) FAIL: gdb.base/callfwmall.exp: p t_string_values("string 1","string 2") p t_string_values("string 1",string_val2) evaluation of this expression requires the program to have a function "malloc". The following patch uses a new 'gdb,nomalloc' configuration variable to check whether these 't_string_values' tests can be made or not. Can you approve this patch?

I've committed the following patch that fixes the 'return' command for HC11/HC12. - When poping the frame, the stack pointer was not set correctly, - During 68HC12 prologue analysis, the pc was not updated for some instructions - The save address of registers saved during the prologue was not correct (need to take into account the stack correction for HC11) Stephane 2001-05-20 Stephane Carrez * m68hc11-tdep.c (m68hc11_pop_frame): Fix stack pointer computation. (m68hc11_analyze_instruction): Update the pc correctly. (m68hc11_guess_from_prologue): Take into account the stack correction for the saving address.

(I know of 34 such test scripts). gdb.base/callfuncs.exp gdb.base/commands.exp gdb.base/condbreak.exp gdb.base/dbx.exp gdb.base/default.exp gdb.base/define.exp gdb.base/ending-run.exp gdb.base/long_long.exp These 8 are trivial. If this goes well, I'll submit some non-trivial patches as well. Some scripts are written with gdb_expect, and they get a lot shorter when I rewrite them with gdb_test. Michael
