* [Feature #18045] Implement size classes for GCPeter Zhu2021-08-251-3/+4
| | | | | | | | | This commits implements size classes in the GC for the Variable Width Allocation feature. Unless `USE_RVARGC` compile flag is set, only a single size class is created, maintaining current behaviour. See the redmine ticket for more details. Co-authored-by: Aaron Patterson <tenderlove@ruby-lang.org>
* [Feature #18045] Remove T_PAYLOADPeter Zhu2021-08-251-3/+0
| | | | | | | This commit removes T_PAYLOAD since the new VWA implementation no longer requires T_PAYLOAD types. Co-authored-by: Aaron Patterson <tenderlove@ruby-lang.org>
* Revert "[Feature #18045] Implement size classes for GC"Peter Zhu2021-08-231-4/+6
| | | | | | This reverts commits 48ff7a9f3e47bffb3e4d067a12ba9b936261caa0 and b2e2cf2dedd104acad8610721db5e4d341f135ef because it is causing crashes in SPARC solaris and i386 debian.

* Mostly recover a Ruby stack trace from a core fileAaron Patterson2020-10-141-0/+163
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the lldb script so it can mostly recover a Ruby stack trace from a core file. It's still missing line numbers and dealing with CFUNCs, but you use it like this: ``` (lldb) rbbt ec rb_control_frame_t TYPE 0x7f6fd6555fa0 EVAL ./bootstraptest/runner.rb error!! 0x7f6fd6555f68 METHOD ./bootstraptest/runner.rb main 0x7f6fd6555f30 METHOD ./bootstraptest/runner.rb in_temporary_working_directory 0x7f6fd6555ef8 METHOD /home/aaron/git/ruby/lib/tmpdir.rb mktmpdir 0x7f6fd6555ec0 BLOCK ./bootstraptest/runner.rb block in in_temporary_working_directory 0x7f6fd6555e88 CFUNC 0x7f6fd6555e50 BLOCK ./bootstraptest/runner.rb block (2 levels) in in_temporary_working_directory 0x7f6fd6555e18 BLOCK ./bootstraptest/runner.rb block in main 0x7f6fd6555de0 METHOD ./bootstraptest/runner.rb exec_test 0x7f6fd6555da8 CFUNC 0x7f6fd6555d70 BLOCK ./bootstraptest/runner.rb block in exec_test 0x7f6fd6555d38 CFUNC 0x7f6fd6555d00 TOP /home/aaron/git/ruby/bootstraptest/test_insns.rb error!! 0x7f6fd6555cc8 CFUNC 0x7f6fd6555c90 BLOCK /home/aaron/git/ruby/bootstraptest/test_insns.rb block in <top (required)> 0x7f6fd6555c58 METHOD ./bootstraptest/runner.rb assert_equal 0x7f6fd6555c20 METHOD ./bootstraptest/runner.rb assert_check 0x7f6fd6555be8 METHOD ./bootstraptest/runner.rb show_progress 0x7f6fd6555bb0 METHOD ./bootstraptest/runner.rb with_stderr 0x7f6fd6555b78 BLOCK ./bootstraptest/runner.rb block in show_progress 0x7f6fd6555b40 BLOCK ./bootstraptest/runner.rb block in assert_check 0x7f6fd6555b08 METHOD ./bootstraptest/runner.rb get_result_string 0x7f6fd6555ad0 METHOD ./bootstraptest/runner.rb make_srcfile 0x7f6fd6555a98 CFUNC 0x7f6fd6555a60 BLOCK ./bootstraptest/runner.rb block in make_srcfile ``` Getting the main execution context is difficult (it is stored in a thread local) so for now you must supply an ec and this will make a backtrace
* Fix lldb disassembler so it works with core filesAaron Patterson2020-10-081-24/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the lldb disassembler script so that it doesn't need a live process when disassembling rb_iseq_t. I also added the PC to the output so you can tell what the VM is executing when it crashed. For example: ``` (lldb) rbdisasm ec->cfp->iseq PC IDX insn_name(operands) 0x56039f0a1720 0000 nop 0x56039f0a1728 0001 getlocal_WC_1( 5 ) 0x56039f0a1738 0003 branchunless( 7 ) 0x56039f0a1748 0005 getlocal_WC_0( 3 ) 0x56039f0a1758 0007 putstring( (VALUE)0x56039f0c7eb8 ) 0x56039f0a1768 0009 opt_send_without_block( (struct rb_call_data *)0x56039f09f140 ) 0x56039f0a1778 0011 pop 0x56039f0a1780 0012 getglobal( ID: 0x7fd7 ) 0x56039f0a1790 0014 branchunless( 7 ) 0x56039f0a17a0 0016 getlocal_WC_0( 3 ) 0x56039f0a17b0 0018 putstring( (VALUE)0x56039f0c7e90 ) 0x56039f0a17c0 0020 opt_send_without_block( (struct rb_call_data *)0x56039f09f150 ) 0x56039f0a17d0 0022 pop 0x56039f0a17d8 0023 getlocal_WC_0( 3 ) 0x56039f0a17e8 0025 putobject( (VALUE)0x56039f0c7e68 ) 0x56039f0a17f8 0027 getlocal_WC_1( 6 ) 0x56039f0a1808 0029 dup 0x56039f0a1810 0030 checktype( 5 ) 0x56039f0a1820 0032 branchif( 4 ) 0x56039f0a1830 0034 dup 0x56039f0a1838 0035 opt_send_without_block( (struct rb_call_data *)0x56039f09f160 ) 0x56039f0a1848 0037 tostring 0x56039f0a1850 0038 putobject( (VALUE)0x56039f0c7e40 ) 0x56039f0a1860 0040 concatstrings( 3 ) 0x56039f0a1870 0042 opt_send_without_block( (struct rb_call_data *)0x56039f09f170 ) 0x56039f0a1880 0044 nop 0x56039f0a1888 0045 leave (lldb) p ec->cfp->pc (const VALUE *) $146 = 0x000056039f0a1848 ``` Here we can see the VM is currently executing `opt_send_without_block` (because the PC is one ahead of the current instruction)

* Rudimentary support for disassembling rb_iseq_tAaron Patterson2020-09-221-0/+197
| | | | | | | | | | | | | | | | | | | | | | | I need to disassemble instruction sequences while debugging, so I wrote this. Usage is like this: ``` (lldb) p iseq (rb_iseq_t *) $147 = 0x0000000101068400 (lldb) rbdisasm iseq 0000 putspecialobject( 3 ) 0002 putnil 0003 defineclass( ID: 0x560b, (rb_iseq_t *)0x1010681d0, 2 ) 0007 pop 0008 putspecialobject( 3 ) 0010 putnil 0011 defineclass( ID: 0x56eb, (rb_iseq_t *)0x101063b58, 2 ) 0015 leave ``` Also thanks a ton to @kivikakk helping me figure out how to navigate LLDB's Python 😆
