| Summary | 0036307: Internal Error 200130121 when compiling x86_64-win64 as of r43457 | ||||
| Description | As of revision r43457, the compiler raises Internal Error 200130121 when you try to "make all" under x86_64-win64. | ||||
| Steps To Reproduce | On a 64-bit Windows platform, run "make distclean all install" from the FPC source directory and observe the internal error trigger at the ppc1.exe stage. | ||||
| Additional Information | Possibly caused by incorrect code generation related to new peephole optimisations that Florian implemented last night. | ||||

|
Bumped severity and priority to the highest levels because it blocks compilation of the compiler on a major architecture. |
|
|
Additional information: - Reverting to SVN revision 43455 (2 revisions earlier) removes the internal error. The only modifications between these two revisions are new optimisations in "compiler\x86\aoptx86.pas". - Internal error does not occur under i386-win32. |
|
|
Confirmed. The error occurs at random places. Several retries did compile complete project. |
|
|
I might be wrong, but revisions 43439-43441 also caused problems on a few platforms (see 0036309). I do not understand all details, but there might be a relation. |
|
|
There are some new optimisations that were implemented in r43456. These appear to produce incorrect machine code for x86-64 platforms. |
|
|
@Mischi: Despite close revision number there is no other relation as far as I can see. |
