Andrew Burgess	51a948fdf0	gdb: Have allocate_target_description return a unique_ptr Update allocate_target_description to return a target_desc_up, a specialisation of unique_ptr. This commit does not attempt to make use of the unique_ptr in the best possible way, in almost all cases we immediately release the pointer from within the unique_ptr and then continue as before. There are a few places where it was easy to handle the unique_ptr, and in these cases I've done that. Everything under gdb/features/* is auto-regenerated. There should be no user visible changes after this commit. gdb/ChangeLog: * arch/aarch32.c (aarch32_create_target_description): Release unique_ptr returned from allocate_target_description. * arch/aarch64.c (aarch64_create_target_description): Likewise. * arch/amd64.c (amd64_create_target_description): Likewise. * arch/arc.c (arc_create_target_description): Likewise. * arch/arm.c (arm_create_target_description): Likewise. * arch/i386.c (i386_create_target_description): Likewise. * arch/riscv.c (riscv_create_target_description): Update return type.

Alan Modra	f9ff65d4df	[GOLD] Increase --split-stack-adjust-size For functions with small (< 256 bytes) stack frames, the current x86 do_calls_non_split ignores --split-stack-adjust-size and, in combination with __morestack_non_split, supplies a non-split-stack function with at least 0x100000 (1M) available stack. On powerpc64, a default of 0x4000 is not large enough to reliably work with the golang testsuite. This increase the default size to the defacto x86 value. * options.h (split_stack_adjust_size): Default to 0x100000.	6 years ago

Simon Marchi	a038ffd88e	gdb: put user-supplied CFLAGS at the end GDB currently doesn't build cleanly with clang (a -Wdeprecated-copy-dtor error). I configured my clang-based GDB build with CXXFLAGS="-Wno-error=deprecated-copy-dtor", so I can use it despite that problem. However, I found that it had no effect. This is because my -Wno-error=Wdeprecated-copy-dtor switch is followed by -Werror in the command line, which switches back all warnings to be errors. If we want the user-supplied C(XX)FLAGS to be able to override flags added by our configure script, the user-supplied C(XX)FLAGS should appear after the configure-supplied flags. This patch moves the user-supplied CXXFLAGS at the very end of the compilation command line, which fixes the problem described above. This means moving it out of INTERNAL_CFLAGS and inlining it in the users of INTERNAL_CFLAGS. I observed the problem when building GDB, but the same problem could happen with GDBserver, so the change is done there too. In GDBserver, INTERNAL_CFLAGS is passed when linking gdb/ChangeLog: * Makefile.in (COMPILE): Add CXXFLAGS. (INTERNAL_CFLAGS_BASE): Remove CXXFLAGS. (check-headers): Add CXXFLAGS. gdbserver/ChangeLog: * Makefile.in (COMPILE): Add CXXFLAGS. (INTERNAL_CFLAGS_BASE): Remove CXXFLAGS. (gdbserver$(EXEEXT)): Add CXXFLAGS.

Anton Kolesov	6d2d7c5668	gdbserver: Add GNU/Linux support for ARC This gdbserver implementation supports ARC ABI v3 and v4 (older ARC ABI versions are not supported by other modern GNU tools or Linux itself). Gdbserver supports inspection of ARC HS registers R30, R58 and R59 - feature that has been added to Linux 4.12. Whether gdbserver build will actually support this feature depends on the version of Linux headers used to build the server. v2 [1]: - Use "this->read_memory ()" instead of "the_target->read_memory ()". - Remove the unnecessary "arch-arc.o:" target from the "Makefile.in". - Got rid of "ntohs()" function and added lots of comments about endianness. - Clarify why "pc" value is read from and saved to different fields in user regs struct. - In function "is_reg_name_available_p()", use a range-based iterator to loop over the registers. - Removed mentioning of issue number that was not related to sourceware. - A few typo's fixed.

Shahab Vahedi	e4bd363f99	arc: Rename "arc_gdbarch_features" struct "arc_gdbarch_features" is a data structure containing information about the ARC architecture: ISA version, register size, etc. This name is misleading, because although it carries the phrase "gdbarch", it has nothing to do with the type/interface in GDB. Traditionaly, "gdbarch" structures are only used for that purpose.

Alex Coplan	05cfb0d8cc	aarch64: Fix bogus type punning in parse_barrier() [PR26699] This patch fixes a bogus use of type punning in parse_barrier() which was causing an assembly failure on big endian LP64 hosts when attempting to assemble "isb sy" for AArch64. The type of the entries in aarch64_barrier_opt_hsh is aarch64_name_value_pair. We were incorrectly casting this to the locally-defined asm_barrier_opt which has a wider type (on LP64) for the second member. This happened to work on little-endian hosts but fails on LP64 big endian. The fix is to use the correct type in parse_barrier(). This makes the locally-defined asm_barrier_opt redundant, so remove it. gas/ChangeLog: * config/tc-aarch64.c (asm_barrier_opt): Delete.

Andrew Burgess	043f5c63f0	sim: Fix autoreconf errors in sim/ directory Run autoreconf in sim/ directory and you'll see some errors. The problem is that autoreconf (a perl script) does not evaluate the value passed as an argument to AC_CONFIG_AUX_DIR, so something like: AC_CONFIG_AUX_DIR(`cd $srcdir;pwd`/../..) does not do the right thing inside autoreconf, my understanding is that changing to something like this is fine: AC_CONFIG_AUX_DIR(../..) the generated configure seems to check the value passed, and the value passed relative to the source directory, so I think we get basically the same behaviour as before. sim/testsuite/ChangeLog: * configure: Regnerate. * configure.ac (AC_CONFIG_AUX_DIR): Update. sim/testsuite/d10v-elf/ChangeLog: * configure: Regnerate. * configure.ac (AC_CONFIG_AUX_DIR): Update. sim/testsuite/frv-elf/ChangeLog: * configure: Regnerate. * configure.ac (AC_CONFIG_AUX_DIR): Update. sim/testsuite/m32r-elf/ChangeLog: * configure: Regnerate. * configure.ac (AC_CONFIG_AUX_DIR): Update. sim/testsuite/mips64el-elf/ChangeLog: * configure: Regnerate. * configure.ac (AC_CONFIG_AUX_DIR): Update.	6 years ago
Andrew Burgess	31a8f60f2f	gdb: handle unmapped overlays in find_pc_line I configured and built an m32r-elf toolchain, and ran the gdb.base/overlays.exp test. I saw a couple of errors where GDB would place a breakpoint in the wrong place when placing a breakpoint using a function name, for example in this function: /* 1 / int foo (int x) / 2 / { / 3 / if (x) / 4 / return some_global_variable; / 5 / else / 6 / return 0; / 7 / } GDB would place the breakpoint on line 2 instead of line 3. The issue is that GDB was failing to skip the prologue correctly. The reason for this is that in m32r-tdep.c:m32r_skip_prologue, we first use find_pc_partial_function to find the functions start and end addresses, then we use find_pc_line to find the start and end of the first line of the function. Currently, if the pc value passed to find_pc_partial_function is in an unmapped overlay then the function start and end addresses that are returned are also the unmapped addresses. However, this is not the case for find_pc_line, here, if the address passed in is in an unmapped overlay then we still get back a symtab_and_line describing the mapped location. What this means is that if a function's mapped location is 0x100 -> 0x120, and its unmapped locations is 0x400 -> 0x420 then we think that the start/end is 0x400 and 0x420 respectively, but the first line might run from 0x100 to 0x108. GDB will then try to scan the prologue starting from 0x400 and ending at 0x108, this immediately gives up as it thinks we have gone past the end of the prologue and the breakpoint is placed at 0x400. In this commit I propose that we change find_pc_line to return addresses in the unmapped range if the address passed in is already in the unmapped range. Now the first line will appear to run from 0x400 to 0x408 and the prologue scanner will correctly find the end of the prologue. With this commit gdb.base/overlays.exp now completely passes with an m32r-elf toolchain. gdb/ChangeLog: symtab.c (find_pc_line): Return unmapped addresses when the requested address is also unmapped.	6 years ago
Andrew Burgess	ed3bdac42c	gdb/testsuite: allow gdb.base/overlays.exp to compile for m32r The gdb.base/overlays.exp test is only currently supported on m32r baremetal targets, however, when I configure a toolchain for m32r-elf the test does not compile. This commit updates the linker script, fixes some TCL errors in the exp file, and adds some missing includes to the source file so that the test does compile. With this test, when run against an m32r-elf toolchain the test mostly passes, but there are a couple of failures, these are GDB issues and will be addressed in a later commit. gdb/testsuite/ChangeLog: * gdb.base/m32r.ld: Remove SEARCH_DIR line. Add MEMORY regions, make use of regions throughout. * gdb.base/overlays.exp: Enclose string with variableds in "..", not {...}. * gdb.base/ovlymgr.c: Add 'string.h' and 'stdlib.h' includes.	6 years ago
