2017-08-01[GOLD] PowerPC recreate eh_frame for stubs on each relax passAlan Modra6-18/+137
There is a very small but non-zero probability that a stub group contains stubs on one relax pass, but does not on the next. In that case we would get an FDE covering a zero length address range. (Actually, it's even worse. Alignment padding for stubs can mean the address for the non-existent stubs is past the end of the original section to which stubs are attached, and due to the way do_plt_fde_location calculates the length we can get a negative length.) Fixing this properly requires removing the FDE. Also, I have been implementing the __tls_get_addr_opt support for gold, and that stub needs something other than the default FDE. The necessary FDE will depend on the offset to the __tls_get_addr_opt stub, which of course can change during relaxation. That means at the very least, rewriting the FDE on each pass, possibly changing the FDE size. I think that is better done by completely recreating PLT eh_frame FDEs. * ehframe.cc (Fde::operator==): New.

2017-07-31[GOLD] PowerPC --no-tls-optimizeAlan Modra3-15/+42
This adds a --no-tls-optimize option for people who want to keep __tls_get_addr calls in an executable rather than optimizing such code sequences to IE/LE. Also tidy some formatting errors, rename a variable to better reflect its use, and tweak two functions that create pairs of GOT entries to first check whether the GOT entry already exists before potentially inserting the header via reserve(2). Without the check it is possible to waste one GOT entry. * options.h (no_tls_optimize): New powerpc option. * powerpc.cc (Target_powerpc::abiversion, set_abiversion): Formatting.

2017-07-31Fix documentation about rot agent expression bytecodeSimon Marchi2-2/+9
The rot agent expression bytecode rotates the three items on the top of the stack. It is not clear which way the rotation is. However, the documentation currently shows this as the effect of the instructions: a b c => c b a which doesn't make sense, since the value b doesn't move. The two valid possibilities I see are a b c => b c a a b c => c a b depending on which way you rotate. When looking at the gdbserver code, the top of the stack becomes the third item, and the next-to-top item becomes the top. So the second form would be the right one, since in this notation the top of the stack is the rightmost element: a b c => c a b I adjusted the symbolic description and added a bit of text to make it more obvious. gdb/doc/ChangeLog: * agentexpr.texi (rot): Fix symbolic description, improve textual description.

2017-07-26Lazily and dynamically create i386-linux target descriptionsYao Qi5-34/+112
Instead of using pre-generated target descriptions, this patch changes GDB to lazily and dynamically create target descriptions according to the target hardware capability (xcr0 in i386). This support any combination of target features. Some reg in target description has "regnum" attribute, so its register number is got from the attribute value instead from sequential allocation. <reg name="xmm0" bitsize="128" type="vec128" regnum="32"/> when target description is created, it should match the regnum, so this patch adds a new field m_next_regnum to track it, if attribute number is greater than the m_next_regnum, print the code to set register number explicitly. gdb: 2017-07-26 Yao Qi <yao.qi@linaro.org> * i386-linux-tdep.c: Don't include features/i386/i386-*linux.c.

2017-07-26Generate c for feature instead of tdescYao Qi10-12/+425
This patch changes Makefile and command "maint print c-files" so that GDB can print c files for features instead target description. Previously, we feed GDB a target description xml file, which generate c files including multiple features. With this patch, in Makefile, we wrap each feature xml file, and create a temp target description which include only one feature. Then, adjust the target description printer for them, and print a c function for each given feature, so that we can use these c functions later to create target description in a flexible way. gdb: 2017-07-26 Yao Qi <yao.qi@linaro.org> * features/Makefile (CFILES): Rename with TDESC_CFILES.

2017-07-26Use visitor pattern for "maint print c-tdesc"Yao Qi96-558/+764
Target description can be modeled as a tree, the target description is the root node, features are children nodes, registers and types are grand-children nodes. So command "maint print c-tdesc" in effect traverse/visit each node, and print them in c. This can be implemented by visitor pattern, this is the first reason. Secondly, I want to this command prints c files in a different way for some specific xml files, but still print c files the same way for the rest of xml files. Third, I even want to print xml files from target descriptions, so that GDBserver can use it to reply GDB's query qXfer:features:read:target.xml. gdb: 2017-07-26 Yao Qi <yao.qi@linaro.org> * target-descriptions.c (tdesc_element_visitor): New class.

2017-07-26Add optional argument to command "maint prints c-tdesc"Yao Qi6-14/+44
Nowadays, we need two steps to print c files for xml target description, that is, 1) read xml target description in, update the current tdesc, 2) visit the current tdesc, print the c file. It is unnecessary to involve in current tdesc, and some validations in each gdbarch are performed unnecessarily, which will reject some target descriptions if they are missing some mandatory feature. This patch adds an optional argument to "maint print c-tdesc", which is an XML file target description, so that we can combine the two steps above into one step, and don't have to involve in global current tdesc. gdb: 2017-07-26 Yao Qi <yao.qi@linaro.org> * NEWS: Mention it. * features/Makefile (%.c: %.xml): Pass the xml file name to command "maint print c-tdesc". * target-descriptions.c (maint_print_c_tdesc_cmd): Get file name from 'arg'. gdb/doc: 2017-07-26 Yao Qi <yao.qi@linaro.org> * gdb.texinfo (Maintenance Commands): Document optional argument of "maint print c-tdesc".

2017-07-26Add enum for result of fast_tracepoint_collectingSimon Marchi5-44/+91
I got confused by the result value of fast_tracepoint_collecting, while it sounds like it would return true/false (whether the thread is collecting or not), it actually returns: 0: not collecting 1: in the jump pad, before the relocated instruction 2: in the jump pad, at or after the relocated instruction To avoid confusion, I think it would be nice to make it return an enum. If you can help find a shorter but still relavant name, it would be awesome. Otherwise, we'll go with that, fast_tpoint_collect_result, which is at least consistent with the existing fast_tpoint_collect_status. gdb/gdbserver/ChangeLog: * tracepoint.h (enum class fast_tpoint_collect_result): New enumeration. (fast_tracepoint_collecting): Change return type to fast_tpoint_collect_result. * tracepoint.c (fast_tracepoint_collecting): Likewise. * linux-low.h: Include tracepoint.h.

2017-07-25[ARM] Access FPSCR on vfpv2Yao Qi2-2/+11
GDB can fetch or store FPSCR on vfpv3, which has 32 VFP registers, but fail to do so on vfpv2, which has 16 VFP registers. GDB code is incorrect for vfpv2, else if (tdep->vfp_register_count > 0 && regno >= ARM_D0_REGNUM && regno <= ARM_D0_REGNUM + tdep->vfp_register_count) while FPSCR register number is defined as ARM_D0_REGNUM + 32. ARM_D0_REGNUM, /* VFP double-precision registers. */ ARM_D31_REGNUM = ARM_D0_REGNUM + 31, ARM_FPSCR_REGNUM, The code above uses "<=" rather than "<", in order to put FPSCR in the range, but it is only correct when tdep->vfp_register_count is 32. On vpfv2, it is 16, and FPSCR is out of the range, so fetch_vfp_regs or store_vfp_regs are not called. gdb: 2017-07-25 Yao Qi <yao.qi@linaro.org> PR tdep/21717 * arm-linux-nat.c (arm_linux_fetch_inferior_registers): Update condition for FPSCR.
