[lldb/cmake] Implicitly pass arguments to llvm_add_library (#142583) If we're not touching them, we don't need to do anything special to pass them along -- with one important caveat: due to how cmake arguments work, the implicitly passed arguments need to be specified before arguments that we handle. This isn't particularly nice, but the alternative is enumerating all arguments that can be used by llvm_add_library and the macros it calls (it also relies on implicit passing of some arguments to llvm_process_sources). | 1 年前 | |
[lldb][RISCV] fix LR/SC atomic sequence handling in lldb-server (#146072) lldb-server had limited support for single-stepping through the lr/sc atomic sequence. This patch enhances that support for all possible atomic sequences. The previous version contained an incorrect regex pattern in the test, causing the riscv-specific test to run on other platforms. This reland fixes the regex (see lldb/test/API/riscv/step/TestSoftwareStep.py) | 1 年前 | |
[lldb-server/linux] Use waitpid(-1) to collect inferior events This is a follow-up to D116372, which had a rather unfortunate side effect of making the processing of a single SIGCHLD quadratic in the number of threads -- which does not matter for simple applications, but can get really bad for applications with thousands of threads. This patch fixes the problem by implementing the other possibility mentioned in the first patch -- doing waitpid(-1) centrally and then routing the events to the correct process instance. The "uncollected" threads are held in the process factory class -- which I've renamed to Manager for this purpose, as it now does more than creating processes.

[lldb][FreeBSD][AArch64] Enable register field detection (#85058) This extends the existing register fields support from AArch64 Linux to AArch64 FreeBSD. So you will now see output like this: (lldb) register read cpsr cpsr = 0x60000200 = (N = 0, Z = 1, C = 1, V = 0, DIT = 0, SS = 0, IL = 0, SSBS = 0, D = 1, A = 0, I = 0, F = 0, nRW = 0, EL = 0, SP = 0) Linux and FreeBSD both have HWCAP/HWCAP2 so the detection mechanism is the same and I've renamed the detector class to reflect that. I have confirmed that FreeBSD's treatment of CPSR (spsr as the kernel calls it) is similair enough that we can use the same field information. (see sys/arm64/include/armreg.h and PSR_SETTABLE_64) For testing I've enabled the same live process test as Linux and added a shell test using an existing FreeBSD core file. Note that the latter does not need XML support because when reading a core file we are not sending the information via target.xml, it's just internal to LLDB. | 2 年前 | |
[lldb] Turn lldb_private::Status into a value type. (#106163) This patch removes all of the Set.* methods from Status. This cleanup is part of a series of patches that make it harder use the anti-pattern of keeping a long-lives Status object around and updating it while dropping any errors it contains on the floor. This patch is largely NFC, the more interesting next steps this enables is to: 1. remove Status.Clear() 2. assert that Status::operator=() never overwrites an error 3. remove Status::operator=() Note that step (2) will bring 90% of the benefits for users, and step (3) will dramatically clean up the error handling code in various places. In the end my goal is to convert all APIs that are of the form ResultTy DoFoo(Status& error) to llvm::Expected<ResultTy> DoFoo() How to read this patch? The interesting changes are in Status.h and Status.cpp, all other changes are mostly perl -pi -e 's/\.SetErrorString/ = Status::FromErrorString/g' $(git grep -l SetErrorString lldb/source) plus the occasional manual cleanup. | 1 年前 | |
[lldb][FreeBSD] Fix NativeRegisterContextFreeBSD_{arm,mips64,powerpc} declarations (#101403) Similar to #97796, fix the type of the native_thread parameter for the arm, mips64 and powerpc variants of NativeRegisterContextFreeBSD_*. Otherwise, this leads to compile errors similar to: lldb/source/Plugins/Process/FreeBSD/NativeRegisterContextFreeBSD_powerpc.cpp:85:39: error: out-of-line definition of 'NativeRegisterContextFreeBSD_powerpc' does not match any declaration in 'lldb_private::process_freebsd::NativeRegisterContextFreeBSD_powerpc' 85 | NativeRegisterContextFreeBSD_powerpc::NativeRegisterContextFreeBSD_powerpc( | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | 2 年前 | |
[lldb][AArch64] Add HWCAP3 to register field detection (#145029) This will be used to detect the presence of Arm's new Memory Tagging store only checking feature. This commit just adds the plumbing to get that value into the detection function. FreeBSD has not allocated a number for HWCAP3 and already has AT_ARGV defined as 29. So instead of attempting to read from FreeBSD processes, I've explicitly passed 0. We don't want to be reading some other entry accidentally. If/when FreeBSD adds HWCAP3 we can handle it like we do for AUXV_FREEBSD_AT_HWCAP. No extra tests here, those will be coming with the next change for MTE support. | 1 年前 | |
