Carlo Bramini	69b1ffdb01	sim/aarch64: Fix register ordering bug in blr (PR sim/25318) A comment in the implementation of blr says: /* The pseudo code in the spec says we update LR before fetching. the value from the rn. / With 'rn' being the register holding the destination address. This may have been true at one point, but the ISA manual now clearly shows the destination register being read before the link register is written.

Shahab Vahedi	1d5d29e73f	gdb: Catch exceptions if the source file is not found The source_cache::ensure method may throw an exception through the invocation of source_cache::get_plain_source_lines. This happens when the source file is not found. The expected behaviour of "ensure" is only returning "true" or "false" according to the documentation in the header file. So far, if gdb is in source layout and a file is missing, you see some outputs like below: ,---------------------------------------------. \| test.c file is loaded in the source window. \| \| \| \| int main() \| \| ... \| \|---------------------------------------------\| \| Remote debugging using :1234 \| \| __start () at /path/to/crt0.S:141 \| \| /path/to/crt0.S: No such file or directory. \| \| (gdb) p/x $pc \| \| $1 = 0x124 \| \| (gdb) n \| \| /path/to/crt0.S: No such file or directory. \| \| (gdb) p/x $pc \| \| $2 = 0x128 \| \| (gdb) [pressing arrow-down key] \| \| (gdb) terminate called after throwing an \| \| instance of 'gdb_exception_error' \| `---------------------------------------------' Other issues have been encountered as well [1]. The patch from Pedro [2] which is about preventing exceptions from crossing the "readline" mitigates the situation by not causing gdb crash, but still there are lots of errors printed: ,---------------------------------------------. \| test.c file is loaded in the source window. \| \| \| \| int main() \| \| ... \| \|---------------------------------------------\| \| Remote debugging using :1234 \| \| __start () at /path/to/crt0.S:141 \| \| /path/to/crt0.S: No such file or directory. \| \| (gdb) [pressing arrow-down key] \| \| /path/to/crt0.S: No such file or directory. \| \| (gdb) [pressing arrow-down key] \| \| /path/to/crt0.S: No such file or directory. \| \| (gdb) [pressing arrow-up key] \| \| /path/to/crt0.S: No such file or directory. \| `---------------------------------------------' With the changes of this patch, the behavior is like: ,---------------------------------------------. \| initially, source window is empty because \| \| crt0.S is not found and according to the \| \| program counter that is the piece of code \| \| being executed. \| \| \| \| later, when we break at main (see commands \| \| below), this window will be filled with the \| \| the contents of test.c file. \| \|---------------------------------------------\| \| Remote debugging using :1234 \| \| __start () at /path/to/crt0.S:141 \| \| (gdb) p/x $pc \| \| $1 = 0x124 \| \| (gdb) n \| \| (gdb) p/x $pc \| \| $2 = 0x128 \| \| (gdb) b main \| \| Breakpoint 1 at 0x334: file test.c, line 8. \| \| (gdb) cont \| \| Continuing. \| \| Breakpoint 1, main () at hello.c:8 \| \| (gdb) n \| \| (gdb) \| `---------------------------------------------' There is no crash and the error message is completely gone. Maybe it is good practice that the error is shown inside the source window. I tested this change against gdb.base/list-missing-source.exp and there was no regression. [1] It has also been observed in the past that the register values are not transferred from qemu's gdb stub, see: https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/issues/226 [2] https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=2f267673f0fdee9287e6d404ecd4f2d29da0d2f2 gdb/ChangeLog: * source-cache.c (source_cache::ensure): Surround get_plain_source_lines with a try/catch.

Alok Kumar Sharma	c3b149eb76	gdb/fortran: Allow for using Flang in Fortran testing In lib/fortran.exp, in the helper function fortran_int4, there is currently no support for the LLVM Fortran compiler, Flang. As a result we return the default pattern 'unknown' to match against all 4-byte integer types, which causes many tests to fail. The same is true for all of the other helper functions related to finding a suitable type pattern. This commit adds support for Flang. There should be no change when testing with gfortran. gdb/testsuite/ChangeLog: * lib/fortran.exp (fortran_int4): Handle clang. (fortran_int8): Likewise. (fortran_real4): Likewise.

Andrew Burgess	dcc9fbc6da	gdb/sim: Assert that the simulator ptid is not null_ptid We assign the simulator inferior a fake ptid. If this ptid is ever set to null_ptid then we are going to run into problems - the simulator ptid is what we return from gdbsim_target::wait, and this in turn is used to look up the inferior data with a call to find_inferior_pid, which asserts the pid is not 0 (which it is in null_pid). This commit adds an assert that the simulator's fake pid is not null_ptid. There should be no user visible changes after this commit. gdb/ChangeLog: * remote-sim.c (sim_inferior_data::sim_inferior_data): Assert that we don't set the fake simulator ptid to the null_ptid.

Alan Modra	24872cb302	Minor fix for R_PPC_VLE_ADDR20 It is incorrect to "continue" in the ppc_elf_relocate_section reloc processing loop except when editing or deleting relocs. The normal loop processing arranges to write the relocs if shuffling them over a deleted entry. Deleting only happens for debug sections currently and those sections won't contain R_PPC_VLE_ADDR20 relocs, so this patch doesn't fix a bug that would trigger with any normal object file. * elf32-ppc.c (ppc_elf_relocate_section): After applying R_PPC_VLE_ADDR20, goto copy_reloc.	7 years ago

Tom de Vries	780636aec0	[gdb/testsuite] Use non-capturing parentheses for inferior_exited_re The inferior_exited_re regexp uses capturing parentheses by default: ... set inferior_exited_re "(\\\[Inferior \[0-9\]+ \$.\$ exited)" ... The parentheses are there to be able to use the expression as an atom, f.i., to have '+' apply to the whole regexp in "${inferior_exited_re}+". But the capturing is not necessary, and it can be confusing because it's not obvious in a regexp using "$inferior_exited_re (bla\|bli)" that the first captured expression is in $inferior_exited_re. Replace by non-capturing parentheses. If we still want to capture the expression, we can simply (and more clearly) use "($inferior_exited_re)".

Alok Kumar Sharma	e409c542cc	Fixed gdb to print arrays with very high indexes In the function f77_print_array_1, the variable 'i' which holds the index is of datatype 'int', while bounds are of datatype LONGEST. Due to size of int being smaller than LONGEST, the variable 'i' stores incorrect values for high indexes (higher than max limit of int). Due to this issue in sources, two abnormal behaviors are seen while printing arrays with high indexes (please check array-bounds-high.f90) For high indexes with negative sign, gdb prints empty array even if the array has elements. (gdb) p arr $1 = () For high indexes with positive sign, gdb crashes. We have now changed the datatype of 'i' to LONGEST which is same as datatype of bounds. gdb/ChangeLog: * f-valprint.c (f77_print_array_1): Changed datatype of index variable to LONGEST from int to enable it to contain bound values correctly. gdb/testsuite/ChangeLog: * gdb.fortran/array-bounds-high.exp: New file. * gdb.fortran/array-bounds-high.f90: New file.

Maciej W. Rozycki	ee98c0daf9	RISC-V/Linux/native: Determine FLEN dynamically Fix RISC-V native Linux support to handle a 64-bit FPU (FLEN == 64) with both RV32 and RV64 systems, which is a part of the current Linux ABI for hard-float systems, rather than assuming that (FLEN == XLEN) in target description determination and that (FLEN == 64) in register access. We can do better however and not rely on any particular value of FLEN and probe for it dynamically, by observing that the PTRACE_GETREGSET ptrace(2) call will only accept an exact regset size, and that will reflect FLEN. Therefore iterate over the call in target description determination with a geometrically increasing regset size until a match is marked by a successful ptrace(2) call completion or we run beyond the maximum size we can support. Update register accessors accordingly, using FLEN determined to size the buffer used for NT_PRSTATUS requests and then to exchange data with the regcache. Also handle a glibc bug where ELF_NFPREG is defined in terms of NFPREG, however NFPREG is nowhere defined. gdb/ * riscv-linux-nat.c [!NFPREG] (NFPREG): New macro.

H.J. Lu	a8c4d40b57	ELF: Add support for unique section ID to assembler Clang's integrated assembler supports multiple section with the same name: .section .text,"ax",@progbits,unique,1 nop .section .text,"ax",@progbits,unique,2 nop "unique,N" assigns the number, N, as the section ID, to a section. The valid values of the section ID are between 0 and 4294967295. It can be used to distinguish different sections with the same section name. This is useful with -fno-unique-section-names -ffunction-sections. -ffunction-sections by default generates .text.foo, .text.bar, etc. Using the same string can save lots of space in .strtab. This patch adds section_id to bfd_section and reuses the linker internal bit in BFD section flags, SEC_LINKER_CREATED, for assmebler internal use to mark valid section_id. It also updates objdump to compare section pointers if 2 sections comes from the same file since 2 different sections can have the same section name. bfd/ PR gas/25380 * bfd-in2.h: Regenerated. * ecoff.c (bfd_debug_section): Add section_id. * section.c (bfd_section): Add section_id.
