2014-07-30constify to_openTom Tromey1-2/+2
This makes target_ops::to_open take a const string and then fixes the fallout. There were a few of these I could not build. However I eyeballed it and in any case the fixes should generally be trivial. This is based on the patch to fix up the target debugging for to_open, because that changes gdb to not directly install to_open as the target command 2014-07-30 Tom Tromey <tromey@redhat.com> * bsd-kvm.c (bsd_kvm_open): Constify. * corelow.c (core_open): Constify. * ctf.c (ctf_open): Constify. * dbug-rom.c (dbug_open): Constify. * exec.c (exec_open): Constify. * m32r-rom.c (m32r_open, mon2000_open): Constify. * microblaze-rom.c (picobug_open): Constify. * nto-procfs.c (procfs_open_1, procfs_open, procfs_native_open): Constify. * ppcbug-rom.c (ppcbug_open0, ppcbug_open1): Constify. * record-btrace.c (record_btrace_open): Constify. * record-full.c (record_full_core_open_1, record_full_open_1) (record_full_open): Constify. * remote-m32r-sdi.c (m32r_open): Constify. * remote-mips.c (common_open, mips_open, pmon_open, ddb_open) (rockhopper_open, lsi_open): Constify. * remote-sim.c (gdbsim_open): Constify. * remote.c (remote_open, extended_remote_open, remote_open_1): Constify. * target.h (struct target_ops) <to_open>: Make "arg" const. * tracefile-tfile.c (tfile_open): Constify.
2014-05-05Partially available/unavailable data in requested rangeYao Qi1-1/+10
In gdb.trace/unavailable.exp, an action is defined to collect struct_b.struct_a.array[2] and struct_b.struct_a.array[100], struct StructB { int d, ef; StructA struct_a; int s:1; static StructA static_struct_a; const char *string; }; and the other files are not collected. When GDB examine traceframe collected by the action, "struct_b" is unavailable completely, which is wrong. (gdb) p struct_b $1 = <unavailable> When GDB reads 'struct_b', it will request to read memory at struct_b's address of length LEN. Since struct_b.d is not collected, no 'M' block includes the first part of the desired range, so tfile_xfer_partial returns TARGET_XFER_UNAVAILABLE and GDB thinks the whole requested range is unavailable. In order to fix this problem, in the iteration to 'M' blocks, we record the lowest address of blocks within the request range. If it has, the requested range isn't unavailable completely. This applies to ctf too. With this patch applied, the result looks good and fails in unavailable.exp is fixed. (gdb) p struct_b $1 = {d = <unavailable>, ef = <unavailable>, struct_a = {a = <unavailable>, b = <unavailable>, array = {<unavailable>, <unavailable>, -1431655766, <unavailable> <repeats 97 times>, -1431655766, <unavailable> <repeats 9899 times>}, ptr = <unavailable>, bitfield = <unavailable>}, s = <unavailable>, static static_struct_a = {a = <unavailable>, b = <unavailable>, array = {<unavailable> <repeats 10000 times>}, ptr = <unavailable>, bitfield = <unavailable>}, string = <unavailable>} gdb: 2014-05-05 Yao Qi <yao@codesourcery.com> Pedro Alves <palves@redhat.com> * tracefile-tfile.c (tfile_xfer_partial): Record the lowest address of blocks that intersects the requested range.

2014-04-22Unify ctf_fetch_registers and tfile_fetch_registersYao Qi1-44/+4
Functions ctf_fetch_registers and tfile_fetch_registers have some duplicated code about guessing the PC in regcache. Sometimes, we may change one function and forget to update the other one, like this https://www.sourceware.org/ml/gdb-patches/2014-01/msg00292.html This patch is to move the duplicated code into a new function tracefile_fetch_registers, and let both ctf_fetch_registers and tfile_fetch_registers call it. gdb: 2014-04-22 Yao Qi <yao@codesourcery.com> * tracefile-tfile.c (tfile_fetch_registers): Move the bottom to ... * tracefile.c (tracefile_fetch_registers): ... it.

2014-04-19Call post_create_inferior in ctf_open.Yao Qi1-0/+2
We don't call post_create_inferior at the end of ctf_open. It is an oversight in patch [PATCH 2/2] Create inferior for ctf target. https://sourceware.org/ml/gdb-patches/2014-01/msg01056.html This patch is to call post_create_inferior at the end of ctf_open, like the end of tfile_open. gdb: 2014-04-19 Yao Qi <yao@codesourcery.com> * ctf.c (ctf_open): Call post_create_inferior.
2014-04-19Get trace_regblock_size from metadata instead of eventYao Qi1-34/+22
In ctf trace, for each 'R' block, we save it as a "register" event, as defined below in metadata. event { name = "register"; id = 0; fields := struct { ascii contents[440]; }; } Nowadays, we initialize trace_regblock_size by getting the length of "contents" from a "register" event. However, 'R' block may not exist in traceframe, as a result, "register" event doesn't exist in trace file and trace_regblock_size isn't set. This patch changes to get trace_regblock_size from metadata (or declaration) which always exists. gdb: 2014-04-19 Yao Qi <yao@codesourcery.com> * ctf.c (handle_id): New static variable. (ctf_open_dir): Get handle_id from bt_context_add_trace return value. Get the declaration of event "register" and get length of field "contents".
2014-04-19Add null pointer check in ctf_xfer_partialYao Qi1-1/+1
I find a gdb crash when gdb reads ctf trace. The crash is caused by passing NULL to strcmp. This patch is to add null pointer check, as what we did somewhere else in ctf.c. gdb: 2014-04-19 Yao Qi <yao@codesourcery.com> * ctf.c (ctf_xfer_partial): Check 'name' is NULL before strcmp.
2014-03-22Move the traceframe_available_memory code from memory_xfer_partial_1 down to ↵Yao Qi1-1/+15
the targets As a follow-up to [PATCH 7/8] Adjust read_value_memory to use to_xfer_partial https://sourceware.org/ml/gdb-patches/2014-02/msg00384.html this patch moves traceframe_available_memory down to the target side. After this patch, the gdb core code is cleaner, and code on handling unavailable memory is moved to remote/tfile/ctf targets. In details, this patch moves traceframe_available_memory code from memory_xfer_partial_1 to remote target only, so remote target still uses traceframe_info mechanism to check unavailable memory, and use remote_ops to read them from read-only sections. We don't use traceframe_info mechanism for tfile and ctf target, because it is fast to iterate all traceframes from trace file, so the summary information got from traceframe_info is not necessary. This patch also moves two functions to remote.c from target.c, because they are only used in remote.c. I'll clean them up in another patch. gdb: 2014-03-22 Yao Qi <yao@codesourcery.com> * ctf.c (ctf_xfer_partial): Check the return value of exec_read_partial_read_only, if it is not TARGET_XFER_OK, return TARGET_XFER_UNAVAILABLE. * tracefile-tfile.c (tfile_xfer_partial): Likewise. * target.c (target_read_live_memory): Move it to remote.c.

This patch adjust both ctf and tfile target implementation of to_xfer_partial, to return TARGET_XFER_E_UNAVAILABLE and set *XFERED_LEN if data is unavailable.

2014-02-11Return target_xfer_status in to_xfer_partialYao Qi1-4/+17
This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0". This patch also eliminates the comparison between status and 0. No target implementations to to_xfer_partial adapts this new interface.

2013-12-02gnulib's sys/stat.h always defines S_IRGRP, S_IXGRP, S_IXOTH.Pedro Alves1-12/+1
Confirmed that cross building a mingw gdb still works, and also made sure it was gnulib's sys/stat.h that was defining the values, by hacking the header with #errors where the macros are defined. gdb/ 2013-12-02 Pedro Alves <palves@redhat.com> * ctf.c (ctf_start): Use S_IRGRP, S_IXGRP, S_IXOTH unconditionally.

2013-04-19-Wpointer-sign: ctf.c.Pedro Alves1-7/+8
ctf_save_write's second parameter is gdb_byte *, and all these arguments are 'char *'. Since this function is ultimately just writing host bytes to a local file with fwrite, an alternative would be to change ctf_save_write to take a 'void *' instead of 'gdb_byte *', thus removing the need for any cast (we have more calls with casts than without). gdb/ 2013-04-19 Pedro Alves <palves@redhat.com> * ctf.c (ctf_write_uploaded_tsv, ctf_write_uploaded_tp): Add casts to 'gdb_byte *'.
