* Remove the use of usrToCell in gcMark [backport:1.2] (#17709)zah2021-04-142-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Remove the use of usrToCell in gcMark [backport:1.2] Recently, we've discovered a GC crash resulting from inlining of the memory allocation procs that allowed the compiler to avoid maintaining any references to the "user pointer" on the stack. Instead, a "cell pointer" appeared there and all field accesses were performed with adjusted offsets. This interfered with the ability of the GC to mark the correct cell in the conservative stack scans which lead to premature collection of objects. More details here: https://github.com/status-im/Nim/commit/af69b3ceae16281efd45cbee4ce1bedd14282304 This commit closes another theoretical loophole that may lead to the same problem. If a short proc is accessing both the object and its reference count in a short sequence of instructions, the compiler may be enticed to reduce the number of registers being used by storing only a single pointer to the object and using offsets when reading and writing fields. A perfectly good strategy would be to store only the cell pointer, so the reference count updates can be performed without applying offsets. Accessing the fields of the object requires offsets anyway, but these can be adjusted at compile-time without any loss. Following this strategy will lead to the same problem of marking a wrong cell during the conservative stack scan, leading to premature collection. The problem is avoided by not using `usrToCell` in `gcMark`. Since the cell discovery logic can already handle interior pointers, the user pointers don't need to be adjusted for the GC to function correctly.

* [backport:1.2] Avoid inlining of newObj and newObjRC1 calls (#17582)Miran2021-03-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | This is taken from: https://github.com/status-im/Nim/commit/af69b3ceae16281efd45cbee4ce1bedd14282304 Full original comment: This is to avoid heavy inlining happening when two allocation calls would occur shortly after each other. This inlining would sometimes be accompanied with an optimisation as the compiler is able to see that cellToUsr ending the first allocation call is shortly followed by an usrToCell call. The pointer arithmetic is redundant and the compiler can eliminate it, leaving only the cell address in a register (and later the stack) instead of the actual pointer to the user data, as one would expect. This combined with a GC collect cycle will cause the stack scan to only notice the cell address, which is of no good due to a usrToCell in the gcMark call which shifts that address to an adjacent cell. This means that the actual cell of importance will not get marked and thus cause a premature collection of that cell. BOOM.
