2021-05-17gdb/fortran: test case modified to suit the clang behavior.Bhuvanendra Kumar N2-3/+14
As mentioned in the test case itself, depending on the fortran compiler used, class member names used in the print commands and also output of these print commands varies. Existing print commands and its output are suited for gfortran, hence they were failing with clang compiler and test case was modified accordingly for clang compiler. gdb/testsuite/ChangeLog: * gdb.base/class-allocatable-array.exp: Modified test for clang.
2021-05-17sim: fully merge sim_state_base into sim_stateMike Frysinger43-93/+154
Now that all ports have migrated to the new framework, drop support for the old sim_state_base layout.

2021-05-17sim: invert sim_state storageMike Frysinger33-124/+143
Currently all ports have to declare sim_state themselves in their sim-main.h and then embed the common sim_state_base & sim_cpu in it. This dynamic makes it impossible to share common object code among multiple ports because the core data structure is always different. Let's invert this relationship: common code declares sim_state, and if the port actually needs state on a per-instance basis, it can use the new arch_data field for it. Most ports don't actually use it, so they don't need to declare anything at all. This is the first in a series of changes: it adds a define to select between the old & new layouts, then converts all the ports that don't need custom state over to the new layout.
2021-05-16sim: install library header filesMike Frysinger3-37/+78
We install libsim.a for people to link against, but haven't been installing the header files to for its API. Export them!
2021-05-16sim: switch config.h usage to defs.hMike Frysinger302-169/+923
The defs.h header will take care of including the various config.h headers. For now, it's just config.h, but we'll add more when we integrate gnulib in. This header should be used instead of config.h, and should be the first include in every .c file. We won't rely on the old behavior where we expected files to include the port's sim-main.h which then includes the common sim-basics.h which then includes config.h. We have a ton of code that includes things before sim-main.h, and it sometimes needs to be that way. Creating a dedicated header avoids the ordering mess and implicit inclusion that shows up otherwise.

2021-05-16CTF: handle forward reference typeWeimin Pan5-27/+562
The problems can be illustrated, with any program, below: (gdb) print main $1 = {main} 0x0 The return type was incorrectly set in read_func_kind_type, with the name of the function, which leads c_type_print_base_1 to print it. In addition, the address of a new function needs to be set with that info in its minimal symtab entry, when the new function is added. After the fix: (gdb) print main $1 = {int ()} 0x4004b7 <main> A new test, gdb.ctf/funcreturn.exp, is added to the testsuite. gdb/ChangeLog: * ctfread.c (new_symbol): Set function address. (read_func_kind_type): Remove incorrect type name setting. Don't copy name returned from ctf_type_ame_raw throughout file. gdb/testsuite/ChangeLog: * gdb.ctf/funcreturn.exp: New file. * gdb.ctf/whatis.c: Copy from gdb.base.

2021-05-15_mul_overflow and get_encoded_valueAlan Modra3-1/+14
A sufficiently mad compiler optimiser can take undefined behaviour according to the C standard as an opportunity to remove code. Since "data + size" might be seen to be past the end of an array, calculating such an expression is UB. _mul_overflow is infrastructure for later patches. * bucomm.h (_mul_overflow): Define. * dwarf.c (get_encoded_value): Avoid pointer UB.

2021-05-14Fix Python pretty-printing bug in RustTom Tromey6-2/+133
An upstream Rust bug notes notes that the Python pretty-printing feature is broken for values that appear as members of certain types in Rust. The bug here is that some of the Rust value-printing code calls value_print_inner, a method on rust_language. This bypasses the common code that calls into Python.

Define a 'connection_num' attribute for Inferior objects. The read-only attribute is the ID of the connection of an inferior, as printed by "info inferiors". In GDB's internal terminology, that's the process stratum target of the inferior.

2021-05-14RISC-V: Check the overflow for %pcrel_lo addend more strictly.Nelson Chu9-13/+60
The %pcrel_lo addend may causes the overflow, and need more than one %pcrel_hi values. But there may be only one auipc, shared by those %pcrel_lo with addends. However, the existing check method in the riscv_resolve_pcrel_lo_relocs, may not be able to work for some special/corner cases. Consider the testcases pcrel-lo-addend-2b. Before applying this patch, I can compile it successfully. But in fact the addend cause the value of %pcrel_hi to be different. This patch try to check the value of %pcrel_hi directly, to make sure it won't be changed. Otherwise, linker will report the following errors, (.text+0xa): dangerous relocation: %pcrel_lo overflow with an addend, the value of %pcrel_hi is 0x1000 without any addend, but may be 0x2000 after adding the %pcrel_lo addend The toolchain regressions, rv64gc-linux/rv64gc-elf/rv32gc-linux/rv32i-elf, pass expectedly and looks fine. bfd/ * elfnn-riscv.c (riscv_resolve_pcrel_lo_relocs): Check the values of %pcrel_hi, before and after adding the addend.

2021-05-14gdb: fix pretty printing max depth behaviourKent Cheung9-37/+77
The 'print max-depth' feature incorrectly causes GDB to skip printing the string representation of pretty printed variables if the variable is stored at a nested depth corresponding to the set max-depth value. This change ensures that it is always printed before checking whether the maximum print depth has been reached. Regression tested with GCC 7.3.0 on x86_64, ppc64le, aarch64. gdb/ChangeLog: * cp-valprint.c (cp_print_value): Replaced duplicate code. * guile/scm-pretty-print.c (ppscm_print_children): Check max_depth just before printing child values.
