Dr Smith C development

What does Dr Smith C Dev set of progs do?

Is there a demo / test of it? thanks

Indeed. It’s essentially Google’s Address sanitiser. You compile the code with a special flag and Norcroft generates function calls immediately before every memory access (ie a branch before every load and store instructions). Dr Smith’s uses that function call to log the access against every memory allocation/memory free to ensure that it is a valid access.

I’ve no idea why Norcroft had that feature – it was in for many years before DrSmith’s was written.

As Rick pointed out in another thread, none of us currently know if it’s suitable for 32-bit code.

There’s also a profiler, but I never really used that.

Does this mean that ‘C’ Norcroft can be made to produce a file of memory accesses – that Dr Smith can make sense of?

What’s the secret incantation?

It hasn’t changed since you last asked about it in 2020, though it’s now on page 123 of the manual because it got a bit fatter.

A sign of its age?

I am hyper-observant, I notice everything. That, unfortunately, is coupled with a really lousy memory with a broken input filter.

Ask me what my evening meals were Monday to Thursday. I pretty much eat the same things so there’s maybe a choice of a half dozen options. Ask me what my evening meals were Monday to Thursday. <facepalm>

Are the Dr Smith progs 26bit only?

I see the progs on CJE site – are they on floppies?

Plus, it’s a reference to the [gap] period

As in the sequence, 2018, 2019, [gap], 2021, 2022…
