@philberty Could you elaborate, here's what I tried: And there's no different. |

Oh, BTW, I fixed "go front-end" to "rust front-end" typo for one or two files., So you'd better check it in my branch. |

Ah sorry i was doing my comparison the wrong way round i see it now |

…imize or target pragmas [PR103012] The following testcases ICE when an optimize or target pragma is followed by a long line (4096+ chars). This is because on such long lines we can't use columns anymore, but the cpp_define calls performed by c_cpp_builtins_optimize_pragma or from the backend hooks for target pragma are done on temporary buffers and expect to get columns from whatever line they appear on (which happens to be the long line after optimize/target pragma), and we run into: #0 fancy_abort (file=0x3abec67 "../../libcpp/line-map.c", line=502, function=0x3abecfc "linemap_add") at ../../gcc/diagnostic.c:1986 #1 0x0000000002e7c335 in linemap_add (set=0x7ffff7fca000, reason=LC_RENAME, sysp=0, to_file=0x41287a0 "pr103012.i", to_line=3) at ../../libcpp/line-map.c:502 #2 0x0000000002e7cc24 in linemap_line_start (set=0x7ffff7fca000, to_line=3, max_column_hint=128) at ../../libcpp/line-map.c:827 #3 0x0000000002e7ce2b in linemap_position_for_column (set=0x7ffff7fca000, to_column=1) at ../../libcpp/line-map.c:898 #4 0x0000000002e771f9 in _cpp_lex_direct (pfile=0x40c3b60) at ../../libcpp/lex.c:3592 #5 0x0000000002e76c3e in _cpp_lex_token (pfile=0x40c3b60) at ../../libcpp/lex.c:3394 #6 0x0000000002e610ef in lex_macro_node (pfile=0x40c3b60, is_def_or_undef=true) at ../../libcpp/directives.c:601 #7 0x0000000002e61226 in do_define (pfile=0x40c3b60) at ../../libcpp/directives.c:639 #8 0x0000000002e610b2 in run_directive (pfile=0x40c3b60, dir_no=0, buf=0x7fffffffd430 "__OPTIMIZE__ 1\n", count=14) at ../../libcpp/directives.c:589 #9 0x0000000002e650c1 in cpp_define (pfile=0x40c3b60, str=0x2f784d1 "__OPTIMIZE__") at ../../libcpp/directives.c:2513 #10 0x0000000002e65100 in cpp_define_unused (pfile=0x40c3b60, str=0x2f784d1 "__OPTIMIZE__") at ../../libcpp/directives.c:2522 #11 0x0000000000f50685 in c_cpp_builtins_optimize_pragma (pfile=0x40c3b60, prev_tree=<optimization_node 0x7fffea042000>, cur_tree=<optimization_node 0x7fffea042020>) at ../../gcc/c-family/c-cppbuiltin.c:600 assertion that LC_RENAME doesn't happen first. I think the right fix is emit those predefined macros upon optimize/target pragmas with BUILTINS_LOCATION, like we already do for those macros at the start of the TU, they don't appear in columns of the next line after it. Another possibility would be to force them at the location of the pragma. 2021-12-30 Jakub Jelinek <[email protected]> PR c++/103012 gcc/ * config/i386/i386-c.c (ix86_pragma_target_parse): Perform cpp_define/cpp_undef calls with forced token locations BUILTINS_LOCATION. * config/arm/arm-c.c (arm_pragma_target_parse): Likewise. * config/aarch64/aarch64-c.c (aarch64_pragma_target_parse): Likewise. * config/s390/s390-c.c (s390_pragma_target_parse): Likewise. gcc/c-family/ * c-cppbuiltin.c (c_cpp_builtins_optimize_pragma): Perform cpp_define_unused/cpp_undef calls with forced token locations BUILTINS_LOCATION. gcc/testsuite/ PR c++/103012 * g++.dg/cpp/pr103012.C: New test. * g++.target/i386/pr103012.C: New test.

I think the better way to review this PR is to double-confirm if my indentation is the same as yours completely. You may pick one or two original files, indent them and compare. Clang-format may be affected if the system maintains multiple clang-format like mine.
