Mike Gulick	4166753056	Fix gdb segv when objfile can't be opened This fixes PR 16577. This patch changes gdb_bfd_map_section to issue a warning rather than an error if it is unable to read the object file, and sets the size of the section/frame that it attempted to read to 0 on error. The description of gdb_bfd_map_section states that it will try to read or map the contents of the section SECT, and if successful, the section data is returned and SIZE is set to the size of the section data. This function was throwing an error and leaving SIZE as-is. Setting the section size to 0 indicates to dwarf2_build_frame_info that there is no data to read, otherwise it will try to read from an invalid frame pointer. Changing the error to a warning allows this to be handled gracefully. Additionally, the error was clobbering the breakpoint output indicating the current frame (function name, arguments, source file, and line number). E.g. Thread 3 "foo" hit Breakpoint 1, BFD: reopening /tmp/jna-1013829440/jna2973250704389291330.tmp: No such file or directory BFD: reopening /tmp/jna-1013829440/jna2973250704389291330.tmp: No such file or directory (gdb) While the "BFD: reopening ..." messages will still appear interspersed in the breakpoint output, the current frame info is now displayed: Thread 3 "foo" hit Breakpoint 1, BFD: reopening /tmp/jna-1013829440/jna1875755897659885075.tmp: No such file or directory BFD: reopening /tmp/jna-1013829440/jna1875755897659885075.tmp: No such file or directory warning: Can't read data for section '.eh_frame' in file '/tmp/jna-1013829440/jna1875755897659885075.tmp' do_something () at file.cpp:80 80 { (gdb)	9 years ago
Simon Marchi	4d9b86e175	Make linux_ptrace_attach_fail_reason return an std::string This patch makes linux_ptrace_attach_fail_reason and linux_ptrace_attach_fail_reason_string return std::string. It also replaces usages of struct buffer with std::string. This allows getting rid of a cleanup in in linux_ptrace_attach_fail_reason_string and simplifies the code in general. Something that looks odd to me is that in linux_ptrace_attach_fail_reason, if the two messages are appended, there is no separating space or \n, so the result won't be very nice. I left it as-is for now though. gdb/ChangeLog: * nat/linux-ptrace.h (linux_ptrace_attach_fail_reason): Return std::string.

Alan Modra	9e390558ce	PowerPC PLT stub tidy This is in preparation for the next patch adding Spectre variant 2 mitigation for PowerPC and PowerPC64. Besides tidying code involved in stub output (to reduce the number of places where bctr is output), the patch adds some user visible features: 1) PowerPC64 ELFv2 global entry stubs now are aligned under the control of --plt-align, with a default alignment of 32 bytes. 2) PowerPC64 __glink_PLTresolve is no longer padded out with nops. 3) PowerPC32 PLT stubs are aligned under the control of --plt-align, with the default alignment being 16 bytes as before. 4) The PowerPC32 branch/nop table emitted before __glink_PLTresolve is now smaller in many cases. It was sized incorrectly when the __tls_get_addr_opt stub was used, and unnecessarily included space for local ifuncs. bfd/ * elf32-ppc.c (GLINK_ENTRY_SIZE): Add parameters, handle __tls_get_addr_opt, and alignment sizing.

Tom Tromey	86d6a90c58	Fix scm-ports.exp regression In https://sourceware.org/ml/gdb-patches/2017-12/msg00215.html, Jan pointed out that the scalar printing patches caused a regression in scm-ports.exp on x86. What happens is that on x86, this: set sp_reg [get_integer_valueof "\$sp" 0] ... ends up setting sp_reg to a negative value, because get_integer_valueof uses "print/d": print /d $sp $1 = -11496 Then later the test suite does: gdb_test "guile (print (seek rw-mem-port (value->integer sp-reg) SEEK_SET))" \ "= $sp_reg" \ "seek to \$sp" ... expecting this value to be identical to the saved $sp_reg value. However it gets: guile (print (seek rw-mem-port (value->integer sp-reg) SEEK_SET)) = 4294955800 "print" is just a wrapper for guile's format: gdb_test_no_output "guile (define (print x) (format #t \"= ~A\" x) (newline))" The seek function returns a scm_t_off, the printing of which is handled by guile, not by gdb. Tested on x86-64 Fedora 26 using an ordinary build and also a -m32 build. 2018-01-15 Tom Tromey <tom@tromey.com> * gdb.guile/scm-ports.exp (test_mem_port_rw): Use get_valueof to compute sp_reg.	8 years ago
Cary Coutant	930b5f8bfb	Fix -fuse-ld option to accept string argument. PR 22042 complained that garbage text was being printed in the help for the -fuse-ld option; this was caused by passing an empty string to the gettext() function, which sometimes returns garbage when passed an empty string. The quick fix was to replace "" with NULL as the helparg, but that changed the parsing of the option, as gold uses the helparg to determine whether an option takes an argument. This patch adds a non-empty helparg string to fix both problems. gold/ PR gold/22694 * options.h (-fuse-ld): Add correct helparg.	8 years ago
Thomas Preud'homme	cf3cf39d53	[ARM] Add new macro for Thumb-only opcodes Armv8-M Security Extensions introduced some Thumb-only opcodes (eg. sg). These are defined using the TUE and TCE macros, setting the Arm execution state related fields to 0/NULL. This patch adds 2 new macros to avoid filling this field and clearly identify Thumb-only instructions. 2018-01-15 Thomas Preud'homme <thomas.preudhomme@arm.com> gas/ * config/tc-arm.c (ToC): Define macro.

Thomas Preud'homme	2875ce2b55	[ARM] Enable conditional Armv8-M instructions Newly introduced instructions common to ARMv8-M Baseline and Mainline are currently all marked as unconditional. However, all instructions but sg (ie. blxns, bxns, tt, ttt, tta, ttat, vlldm and vlstm) do actually support conditional execution. This patch fixes the definition of these instructions accordingly. 2018-01-15 Thomas Preud'homme <thomas.preudhomme@arm.com> gas/ * config/tc-arm.c (insns): Make blxns, bxns, tt, ttt, tta, ttat, vlldm and vlstm conditionally executable and reindent parameters. * testsuite/gas/arm/archv8m-cmse-main.s: Add conditional version of aforementionned instructions.	8 years ago
Thomas Preud'homme	df9909b867	[ARM] No IT usage deprecation for ARMv8-M Deprecations related to the use of the IT instruction introduced in Armv8-A do not apply to Armv8-M Baseline and mainline. However the warning logic do not distinguish between the various profiles and warn whenever the architecture version is 8. This patch adds a check to exclude M profile architectures from this warning. This works as expected when -march is specified on the command-line or a .arch/.cpu directive exist. However, in autodetection mode the CPU/architecture targeted is only known once the instructions have been all processed but this code is run when IT instruction is processed. It is therefore not possible to distinguish between Armv8-M and Armv8-A in that mode. The approach chosen here is not to warn in autodetection mode. The udf.d testcase that relied on that behavior to test deprecation warning for Armv8-A is therefore updated to explicitely pass -march=armv8-a. 2018-01-15 Thomas Preud'homme <thomas.preudhomme@arm.com> gas/ * config/tc-arm.c (it_fsm_post_encode): Do not warn if targeting M profile architecture or if in autodetection mode.

Pedro Alves	eea61984ab	Add testcase for GDB hang fixed by previous commit This adds a testcase for the previous commit. The regression was related to in-line step overs. The reason we didn't see it on native x86-64/s390 GNU/Linux testing is that native debugging uses displaced stepping by default (because native debugging defaults to "maint set target-non-stop on"), unlike remote debugging. So in order to trigger the bug with native debugging as well, the testcase disables displaced stepping explicitly. Also, instead of using watchpoints to trigger the regression, the testcase uses a breakpoint at address 0, which should be more portable. gdb/testsuite/ChangeLog: 2018-01-12 Pedro Alves <palves@redhat.com> * gdb.base/continue-after-aborted-step-over.c: New. * gdb.base/continue-after-aborted-step-over.exp: New.	8 years ago
Andreas Arnez	bdf2a94aa5	Fix GDB hang with remote after error from resume Since this commit -- Fix PR18360 - internal error when using "interrupt -a" (https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=c65d6b55) -- the testsuite shows long delays on s390 with native-gdbserver when executing certain tests, such as watchpoints.exp. These hangs have been discussed before in the context of buildbot problems, see here: https://sourceware.org/ml/gdb-patches/2017-12/msg00413.html The problem can easily be triggered by stopping on a breakpoint, then setting impossible watchpoints, and finally doing "continue". Then, after having set the step-over state (in keep_going_pass_signal in infrun.c), GDB tries to insert breakpoints and watchpoints into the inferior. This fails, and the "continue" command is aborted. But the step-over state is not cleared in this case, which causes future step-over attempts to be skipped since GDB thinks that "we already have an in-line step-over operation ongoing" (see start_step_over in infrun.c). Thus the next "continue" just goes on to wait for events from the remote, which will never occur. The problem can also be reproduced on amd64 with native-gdbserver, using the following change to watchpoints.exp: -- >8 -- --- a/gdb/testsuite/gdb.base/watchpoints.exp +++ b/gdb/testsuite/gdb.base/watchpoints.exp @@ -61,2 +61,3 @@ with_test_prefix "before inferior start" { gdb_test "watch ival3" "." "" + gdb_test "watch (char \[256\] ) main" -- >8 -- To fix the hang, this patch clears the step-over info when insert_breakpoints has failed. Of course, with native-gdbserver the watchpoints.exp test case still causes many FAILs on s390, because gdbserver does not support watchpoints for that target. This is a separate issue. gdb/ChangeLog: 2018-01-12 Andreas Arnez <arnez@linux.vnet.ibm.com> infrun.c (keep_going_pass_signal): Clear step-over info when insert_breakpoints fails.	8 years ago
