* unpack.c: Cast negative signed offset to signedHEADmasterTomasz Kramkowski2022-11-021-1/+1
| | | | | | | | | | As N1570ยง6.5.16.2p3 states, E1 += E2 is equivalent to E1 = E1 + (E2). This means that E1 + (E2) will be subject to (6.5.6p4) "the usual arithmetic conversions". Since both types have equal integer conversion rank (6.3.1.1p1), E1 which was intmax_t will first be converted to uintmax_t before being added to (E2). This is not the intended result as it relies on integer wrapping behaviour again. Casting E2 to intmax_t first prevents the conversion of E1 and produces the correct result.

* clean: always manually remove, use redo-targets to checkTomasz Kramkowski2021-09-211-6/+15
| | | | | | | | | clean will now always use the non-redo-targets clean method, but if redo-targets is available it will check that there's nothing missing from the logic. This isn't bulletproof but it's better than having a working clean when using a redo with redo-targets and then having a broken clean logic because I forgot to add something when not using a redo-targets redo.
* pack: Simplify signed integer packing calculationTomasz Kramkowski2021-08-141-7/+1
| | | | | | | | | | | | | Because of the fact that uintmax_t guarantees at least a full 64 bit width and because of C's behavior when a signed type is converted to an unsigned type and the value is out of range, the new code just sign-extends and converts to a uintmax_t wide two's complement signed value. As an aside, the old code was written forgetting the fact that that uintmax_t + intmax_t would be first converted to uintmax_t + uintmax_t before being evaluated. The end result was the same except it ended up being offset by 2^8s.

* make [HT]CC full paths for redo-ifchange in .toolTomasz Kramkowski2021-08-112-1/+7
| | | | | | | | | | | | This should force rebuilding targets which depend on tools which have changed in the filesystem and prevent envrionment changes from causing build changes. But this should be documented. Ideally a redo with a redo-always (or more aptly named redo-ifredo) would mark an env target as needing redoing every time you run redo on a deptree which includes it and this would in turn cause rebuilding of things which rely on the environment (like tools which run from the path).

* make do-link executable from /usr/bin/envTomasz Kramkowski2021-08-064-6/+8
| | | | | | | On openbsd the script interpreter of an interpreter script can't be an interpreter script (script(7)) so do-link must be ran with /usr/bin/env which means the type parameter needs to be a variable set in the do file.
* .builds: use my own minimal/do versionTomasz Kramkowski2021-08-065-5/+5

* Define PRIuSIZE to avoid issues compiling with msvcrtTomasz Kramkowski2021-08-053-6/+18
| | | | | | | | On windows and when cross compiling with mingw the standard library only supports C89 which means that print format arguments cannot take "%zu". To fix this, a PRIuSIZE macros is needed which expands to PRIu32 on windows 32 bit and PRIu64 on windows 64 bit.
