2012-10-24remote packet sent after Ravenscar inferior exitedJoel Brobecker2-2/+18
When debugging a program using the Ravenscar profile, the debugger sometimes tries to send the following packet to the remote after the inferior exited. (gdb) c Continuing. [...] Sending packet: $vCont;c:1#13...Ack Packet received: W00 Sending packet: $Hg1#e0...putpkt: write failed: Broken pipe. As the inferior exited, the remote has already disconnected, and thus the operation fails. The reason why GDB sends the package is because the ravenscar-thread module tries to updates the list of threads. But this doesn't make sense, since the program has exited. This patch fixes it. gdb/ChangeLog: * ravenscar-thread.c (ravenscar_wait): Only update the list of threads and inferior_ptid if the inferior is still alive.
2012-10-24[Ada] use lbasename when testing if file is part of Ada runtime.Joel Brobecker2-1/+7
We use a list of regular expressions to match a symtab filenames against the names of the files in the Ada runtime. These regular expressions do assume that the filename is a basename, however. So make sure to evaluate these regular expressions against the symtab's filename. Without this patch, we run into problems when the Ada runtime was built using a project file (through gprbuild). gdb/ChangeLog: * ada-lang.c (is_known_support_routine): Use lbasename when matching the symtab's filename against known_runtime_file_name_patterns.
2012-10-24[Ada] Allow assignment to wide string.Joel Brobecker7-3/+233
Given the following variable declaration... Www : Wide_String := "12345"; ... this patch allows the following assignment to work: (gdb) set variable www := "qwert" Without this patch, the debugger rejects the assignment because the size of the array elements are different: (gdb) set www := "asdfg" Incompatible types in assignment (on the lhs, we have an array of 2-bytes elements, and on the rhs, we have a standard 1-byte string). gdb/ChangeLog: * ada-lang.c (ada_same_array_size_p): New function. (ada_promote_array_of_integrals): New function. (coerce_for_assign): Add handling of arrays where the elements are integrals of a smaller size than the size of the target array element type. gdb/testsuite/ChangeLog: * gdb.ada/set_wstr: New testcase.
2012-10-24off-by-one max exponent computation in convert_doublest_to_floatformatJoel Brobecker5-1/+67
Assuming the following variable definition: long double inp = 2.0; On platforms where "long double" is a double precision IEEE flaoting point, GDB currently behaves as follow: (gdb) set variable inp = 1.6e+308l (gdb) p inp $2 = inf <<<<---- !!!! Instead, the value of "inp" should be printed as: (gdb) p inp $1 = 1.6e+308 The problem is due to a small error in the comparison of the exponent versus the maximum value this exponent can take, causing us to think that the value was too big to fit. But it isn't. gdb/ChangeLog: * doublest.c (convert_doublest_to_floatformat): Fix comparison against maximum exponent value. gdb/testsuite/ChangeLog: * gdb.base/ldbl_e308.c, gdb.base/ldbl_e308.exp: New files.
2012-10-24[Ada] Skip unwind-seh.c when searching first "user" frameJoel Brobecker2-0/+6
On x86_64-windows with GCC 4.7 (using native SEH info), the debugger behaves as follow: (gdb) catch exception unhandled Catchpoint 1: unhandled Ada exceptions (gdb) run Starting program: C:\[...]\b.exe Catchpoint 1, unhandled CONSTRAINT_ERROR at 0x000000000040cc57 in _GCC_specific_handler ([...]) at ../../../src/libgcc/unwind-seh.c:289 [...] This is after compiler the following code: procedure B is begin raise Constraint_Error; end B; ... using the following command: % gnatmake -g b When hitting the exception catchpoint, it should have gone up the stack all the way until finding the frame corresponding to procedure B. But if stopped short because unwind-seh.c is compiled with debugging information, and the debugger is also able to locate that source file. To prevent this from happening, this patch adds unwind-seh.c to the list of files that should be ignored, regardless of other factors. gdb/ChangeLog: * ada-lang.h (ADA_KNOWN_RUNTIME_FILE_NAME_PATTERNS): Add entry for "unwind-seh.c".
2012-10-24[Ada] Pointers to unconstrained arrays inside variant record.Joel Brobecker7-14/+209

2012-10-24[Windows] run program with space in path to exe.Joel Brobecker2-4/+14
The following works... % gdb c:\path to exe\foo.exe (gdb) start ... unless a file or directory called "c:\path" or "c:\path to" exist. This is what happens in the latter case: (gdb) start [...] Error creating process C:\path to exe\foo.exe (error 193). This is because we are calling CreateProcess (et al) without specifying the lpApplicationName, so Windows determines the name of the executable using the second argument, which is the entire command line. This command line is a space-separated list of tokens, so the space in the path to the executable which potentially creates an ambiguity. The ambiguity is automatically resolved unless we're in the situation above. The solution, as suggested by the MSDN documentation for CreateProcess is to quote the executable name. gdb/ChangeLog: * windows-nat.c (windows_create_inferior) [!__CYGWIN__]: New local variable args_len. Quote the name of the executable when computing the command line.
