2012-03-21SEGV during AX eval of OP_DOUBLE (unsupported)Joel Brobecker4-3/+10
To reproduce the problem, simply try the following with any program: (gdb) maintenance agent-eval 1.0 Critical error handler: process [...] terminated due to access violation (this is on Windows; on GNU/Linux, the libc copes better) The problem is quite simple: gen_expr is given an expression that contains an unrecognized operator (OP_DOUBLE in this case). When that happens, it tries to report an error with a string image of the operator in the error message. Conversion of the opcode into a string is done using op_string which, despite its name, probably is not what the author was looking for. This function returns NULL for a lot of the opcodes, thus triggering the crash. There is a function that corresponds to what we are looking for: expprint.c:op_name. It was static, though, so I made it non-static, and used it from ax-gdb.c:gen_expr. gdb/ChangeLog: * expression.h (op_name): Add declaration. * expprint.c (op_name): Remove declaration. Make non-static. * ax-gdb.c (gen_expr): Use op_name instead of op_string.

2012-03-16[Ada] Crash when trying to set value of packed array elementJoel Brobecker9-8/+149
Consider the following declaration: type Small is new Integer range 0 .. 2 ** 4 - 1; type Simple_Array is array (1 .. 4) of Small; pragma Pack (Simple_Array); SA : Simple_Array := (1, 2, 3, 4); Trying to change the value of one of the elements in the packed array causes the debugger to crash: (gdb) set sa(3) := 9 [1] 4880 segmentation fault gdb -q foo The circumstances leading to the crash are as follow: . ada_evaluate_subexp creates a value corresponding to "sa(3)". . ada_evaluate_subexp then tries to assign 9 to this value, and for this calls value_assign (via ada_value_assign). . Because the array is packed, the destination value is 3 bits long, and as a result, value_assign uses the parent to determine that element byte address and offset: | if (value_bitsize (toval)) | { | struct value *parent = value_parent (toval); | | changed_addr = value_address (parent) + value_offset (toval); The destination value (corresponding to "sa(3)") was incorrectly created by ada-lang.c:ada_value_primitive_packed_val, because the "parent" was left as NULL. So, when we try to dereference it to get the parent address, GDB crashed. The first part of the fix therefore consists in setting that field. This required the addition of a new "setter" in value.[hc]. It fixes the crash, but is still not sufficient for the assignment to actually work. The second part of the problem came from the fact that value_assign seems to expect the "child"'s address to be equal to the parent's address, with the difference being the offset. Unfortunately, this requirement was not followed by ada_value_primitive_packed_val, so the second part of the fix consisted in fixing that. Still, this was not sufficient, because it caused a regression when trying to perform an aggregate assignment of a packed array of packed record. The key element here is the nesting of packed entities. Looking at the way ada_value_primitive_packed_val creates the value of each sub-component, one can see that the value's offset is set to the offset compared to the start of the parent. This was meant to match what value_primitive_field does as well. So, with our array of records, if the record offset was 2, and if the field we're interested in that record is at offset 1, the record value's offset would be set to 2, and the field value's offset would be set to 1. But the address for both values would be left to the array's address. This is where things start breaking down, because the value_address function for our field value would return the address of the array + 1, instead of + 3. This is what causes the final issue, here, because ada-lang.c's value_assign_to_component needs to compute the offset of the subcomponent compared to the top-level aggregate's start address (the array in our case). And it does so by subtracting the array's address from the sub-component's address. When you have two levels of packed components, and the mid-level component is at an offset of the top-level component, things didn't work, because the component's address was miscomputed (the parent's offset is missing). The fix consists is fixing value_address to match the work done by value_primitive_field (where we ignore the parent's offset). gdb/ChangeLog: * value.h (set_value_parent): Add declaration. * value.c (set_value_parent): New function. (value_address): If VALUE->PARENT is not NULL, then use it as the base address instead of VALUE->LOCATION.address. * ada-lang.c (ada_value_primitive_packed_val): Keep V's address the same as OBJ's address. Adjust V's offset accordingly. Set V's parent. gdb/testsuite/ChangeLog: * gdb.ada/set_pckd_arr_elt: New testcase.

2012-03-15Problem after hitting breakpoint on Windows (with GDBserver)Joel Brobecker4-9/+43
When debugging on Windows with GDBserver, the debugger starts failing after hitting a breakpoint. For instance: (gdb) b foo Breakpoint 1 at 0x40177e: file foo.adb, line 5. (gdb) cont Continuing. Breakpoint 1, foo () at foo.adb:5 5 Put_Line ("Hello World."); -- STOP (gdb) n Program received signal SIGSEGV, Segmentation fault. 0x00401782 in foo () at foo.adb:5 5 Put_Line ("Hello World."); -- STOP There are two issues: 1. While trying to re-insert a breakpoint that is still inserted in memory, insert_bp_location wipes out the breakpoint location's shadow_contents. As a consequence, we cannot restore the proper instruction when removing the breakpoint anymore. That's why the inferior's behavior changes when trying to resume after the breakpoint was hit. 2. mem-break.c:default_memory_insert_breakpoint passes a breakpoint location's shadow_contents as the buffer for a memory read. This reveals a limitation of the various memory-read target functions. This patch documents this limitation and adjust the two calls that seem to hit that limitation. gdb/ChangeLog: * breakpoint.c (breakpoint_xfer_memory): Add assertion. Update function description. (insert_bp_location): Do not wipe bl->target_info out. * mem-break.c: #include "gdb_string.h".

Use a local buffer instead. * m32r-tdep.c (m32r_memory_insert_breakpoint): Ditto.
