Differences From Artifact [582c735deb]:

• Executable file global/common.sh — part of check-in [e50a476efe] at 2019-08-22 02:52:20 on branch trunk — removed sneaky segfault in x86-64 syscall fn where %r8 (the register that contains the pointer to the syscall arguments from the C syscall wrapper, which need to be copied into the correct registers before the kernel is invoked) gets overwritten if the syscall valency > 5, because of overlapping ccall and syscall ABI argument registers - r8 is clobbered by argument 5 and any further attempts to use it as a ptr segfault at best. also modified the report function so that it immediate cancels compilation if a sub-process reports failure. changed allocator function signatures so they can return a condition code if the kernel reports an error; updated example code so it compiles and runs without fault.

To Artifact [d610091946]:

• File global/common.sh — part of check-in [50b709b0d3] at 2020-01-24 21:18:35 on branch install — Remove the $to check entirely and have more output in install.sh Sourcing a file doesn't need it to be executable, so global/common.sh can have it's executable bit removed and the $to check in it entirely removed. Adds some `say`s to install.sh to let you know it did something and help in case of error. (user: glowpelt, size: 1587) [annotate] [blame] [check-ins using] [more...]
