Alan Modra	c40e31a121	Automatic makefile dependencies for generated ld/e.c This patch modifies genscripts.sh to emit dependency info along with the generated emulation e.c files. This is done by a new source_sh function that records its arg to a file (.deps/e.Tc), using the function whenever a shell script is sourced. Entries in the file are made unique and written to .deps/e.Pc. These files are then included by the Makefile. * Makefile.am (GENSCRIPTS): Pass LIB_PATH as a parameter. Add DEPDIR parameter. (ELF_DEPS, ELF_GEN_DEPS, ELF_X86_DEPS): Delete. (ALL_EMULATION_SOURCES, ALL_64_EMULATION_SOURCES): Depend on $GEN_DEPENDS.

Andrew Burgess	35add35e85	gdb: Fix failure in gdb.base/complex-parts.exp for x86-32 The x86-32 ABI specifies 96-bit long double, this was causing a failure on the test gdb.base/complex-parts.exp. The problem is that GDB tries to find a builtin floating point type of the correct size in order to reuse the name of that type as the name for the components of the complex type being built. Previously GDB was only aware of floating point types sized 32, 64, or 128 bits. This patch teaches GDB how to handle 96 bit floating point type. gdb/ChangeLog: * dwarf2read.c (dwarf2_init_complex_target_type): Handle complex target types of size 96-bits, add some additional comments, and check that the builtin type we found was the correct size.	7 years ago

Andrew Burgess	62253a6147	gdb: Remove LANG_MAGIC The language_defn structure has an la_magic field, this used to be used as a basic check that the language_defn structure had the expected layout - at least the end of the structure was where we expected it to be. This feature only really makes sense if we imagine GDB dynamically loading language support from dynamic libraries, where a version mismatch might cause problems. However, in current GDB language support is statically built into GDB, and since this commit: commit `47e77640be` Date: Thu Jul 20 18:28:01 2017 +0100 Make language_def O(1) the existing (if pointless) check of the la_magic field was removed. There now appears to be no use of the la_magic field, and I propose that we delete it. There should be no user visible changes after this commit. gdb/ChangeLog: * ada-lang.c (ada_language_defn): Remove use of LANG_MAGIC. * c-lang.c (c_language_defn): Likewise.

Andrew Burgess	a9158a863c	gdb/riscv: Remove riscv_type_alignment function Make use of the type_align function and remove riscv_type_alignment as it is no longer needed. I tested this against a number of RV32 and RV64 targets, and I also ran the tests with an assertion in place checking that the old riscv_type_alignment function gives the same answer as the common type_align function - it does, and all the tests still pass. gdb/ChangeLog: * riscv-tdep.c (riscv_type_align): New function.

Andrew Burgess	41077b6625	gdb: Fix alignment computation for structs with only static fields The current code in gdbtypes.c:type_align incorrectly returns 0 as the alignment for a structure containing only static fields. After this patch the correct value of 1 is returned. The gdb.base/align.exp test is extended to cover this case. gdb/ChangeLog: * gdbtypes.c (type_align): A struct with no non-static fields also has alignment of 1. gdb/testsuite/ChangeLog: * gdb.base/align.exp: Extend test to cover structures containing only static fields.	7 years ago
Andrew Burgess	9f0272f854	gdb/riscv: Handle empty C++ structs during argument passing This commit resolves a large number of failures in the test script gdb.base/infcall-nested-structs.exp which were caused by GDB (for RISC-V) incorrectly handling empty C++ structures when preparing arguments for a dummy call, or collecting a return value. The issue is further complicated in that there was a bug in GCC, such that in some cases GCC would generate incorrect code when passing a small structure that contained empty sub-structures. This was fixed in GCC trunk on 5-March-2019, so in order to see the best results with this patch you'll need a recent version of GCC. Anything that used to work should continue to work after this patch, regardless of GCC version being used. The fix in this commit is that GDB now pays more attention to the offset of fields within a structure when preparing arguments as in C++ an empty structure has a non-zero size, this is an example: struct s1 { struct s2 { } empty; int f; }; We previously assumed that 'f' was at offset 0 inside type 's1', however this is not the case in C++ as 's2' has size 1, and with alignment 'f' is likely at some even bigger offset inside 's1'. gdb/ChangeLog: * riscv-tdep.c (riscv_call_arg_complex_float): Fix offset of first component to 0. (riscv_struct_info::riscv_struct_info): Initialise m_offsets member. (riscv_struct_info::analyse): New implementation using new analyse_inner member function. (riscv_struct_info::field_offset): New member function. (riscv_struct_info::m_offsets): New member variable. (riscv_struct_info::analyse_inner): New private member function, takes the old implementation of riscv_struct_info::analyse but extended to track field offsets. (riscv_call_arg_struct): Update the struct folding special cases to handle cases where empty C++ structs, which are non-zero length, are found. (riscv_arg_location): Initialise the length of each location, a non-zero length now indicates the location is in use. (riscv_push_dummy_call): Allow for the first location having a non-zero offset when setting up arguments. (riscv_return_value): Likewise, but for return values.	7 years ago

Tamar Christina	ce12121b63	AArch64: When DF_BIND_NOW don't use TLSDESC GOT value. When using DF_BIND_NOW on AArch64 we don't reserve the GOT slot for a TLSDESC, but we still emitted DT_TLSDESC_GOT and DT_TLSDESC_PLT. This caused random memory corruption as the "special" value of (bfd_vma)-1 would be set for dt_tlsdesc_got. Since we don't have a value of dt_tlsdesc_got I also don't emit DT_TLSDESC_PLT now becuase it would point to an incomplete PLT. To be able to write the PLT entry DT_TLSDESC_GOT is needed and since we don't have one we can't write the PLT entry either. It is my understanding that GLIBC doesn't need these two entries when not lazy loading. Conversely AArch32 does not reserve neither the GOT not the PLT slot when doing DF_BIND_NOW. AArch32 does not need these checks because these values are initialized to 0 and so the if (...) checks don't pass, but on AArch64 these are initialized to (bfd_vma)-1 and thus we need some extra checks. bfd/ChangeLog: PR ld/24302 * elfnn-aarch64.c (elfNN_aarch64_size_dynamic_sections): Don't emit DT_TLSDESC_GOT and DT_TLSDESC_PLT when DF_BIND_NOW.

Kevin Buettner	3f52fdbcb5	Fix amd64->i386 linux syscall restart problem This commit fixes some failures in gdb.base/interrupt.exp when debugging a 32-bit i386 linux inferior from an amd64 host. When running the following test... make check RUNTESTFLAGS="--target_board unix/-m32 interrupt.exp" ... without this commit, I see the following output: FAIL: gdb.base/interrupt.exp: continue (the program exited) FAIL: gdb.base/interrupt.exp: echo data FAIL: gdb.base/interrupt.exp: Send Control-C, second time FAIL: gdb.base/interrupt.exp: signal SIGINT (the program is no longer running) ERROR: Undefined command "". ERROR: GDB process no longer exists === gdb Summary === When the test is run with this commit in place, we see 12 passes instead. This is the desired behavior. Analysis: On Linux, when a syscall is interrupted by a signal, the syscall may return -ERESTARTSYS when a signal occurs. Doing so indicates that the syscall is restartable. Then, depending on settings associated with the signal handler, and after the signal handler is called, the kernel can then either return -EINTR or can cause the syscall to be restarted. In this discussion, we are concerned with the latter case. On i386, the kernel returns this status via the EAX register. When debugging a 32-bit (i386) process from a 64-bit (amd64) GDB, the debugger fetches 64-bit registers even though the process being debugged is 32-bit. Since we're debugging a 32-bit target, only 32 bits are being saved in the register cache. Now, ideally, GDB would save all 64-bits in the regcache and then would be able to restore those same values when it comes time to continue the target. I've looked into doing this, but it's not easy and I don't see many benefits to doing so. One benefit, however, would be that EAX would appear as a negative value for doing syscall restarts. At the moment, GDB is setting the high 32 bits of RAX (and other registers too) to 0. So, when GDB restores EAX just prior to a syscall restart, the high 32 bits of RAX are zeroed, thus making it look like a positive value. For this particular purpose, we need to sign extend EAX so that RAX will appear as a negative value when EAX is set to -ERESTARTSYS. This in turn will cause the signal handling code in the kernel to recognize -ERESTARTSYS which will in turn cause the syscall to be restarted. This commit is based on work by Jan Kratochvil from 2009: https://sourceware.org/ml/gdb-patches/2009-11/msg00592.html Jan's patch had the sign extension code in amd64-nat.c. Several other native targets make use of this code, so it seemed better to move the sign extension code to a linux specific file. I also added similar code to gdbserver. Another approach is to fix the problem in the kernel. Hui Zhu tried to get a fix into the kernel back in 2014, but it was not accepted. Discussion regarding this approach may be found here: https://lore.kernel.org/patchwork/patch/457841/ Even if a fix were to be put into the kernel, we'd still need some kind of fix in GDB in order to support older kernels. Finally, I'll note that Fedora has been carrying a similar patch for at least nine years. Other distributions, including RHEL and CentOS have picked up this change and have been using it too. gdb/ChangeLog: * amd64-linux-nat.c (amd64_linux_collect_native_gregset): New function.

Rainer Orth	a5def729be	Disable R_X86_64_PLT32 generation as branch marker on Solaris/x86 The fix H.J. implemented for PR gas/22791 in the thread starting at [PATCH] x86-64: Treat PC32 relocation with branch as PLT32 https://sourceware.org/ml/binutils/2018-02/msg00065.html is causing problems on Solaris/x86. The native linker is strongly preferred there, and there's no intention of implementing the linker optimization he plans there. Besides, the kernel runtime linker, otherwise has no need to deal with that reloc at all, and instead of adding (possibly even more) workarounds with no benefit, it seems appropriate to disable the R_X86_64_PLT32 generation as branch marker on Solaris/x86 in the first place. The patch itself is trivial, the only complication is adapting the testsuite. Since I've found no way to have conditional sections in the .d files, I've instead used the solution already found elsewhere of having separate .d files for the affected tests in an i386/solaris subdirectory and skipping the original ones.
