| 17:05.59 | prpplague | landley: hey bud |
| 17:06.21 | prpplague | CosmicPenguin: ugh, this week has made me feel totally irrelevant |
| 17:15.16 | landley | prpplague: how goes? |
| 17:15.19 | landley | Irrlevant? |
| 17:15.57 | prpplague | landley: whining and complain about other people just taking my projects and running with them with no credit |
| 17:16.04 | prpplague | landley: it goes |
| 17:16.14 | prpplague | landley: hey i need your compilier brain |
| 17:16.53 | prpplague | landley: a small C app that consists of 3 C files |
| 17:17.31 | prpplague | landley: there any hackish or other tool that can cleaning combine them into one? |
| 17:17.55 | prpplague | landley: i've been experimenting with this - http://kerneis.github.com/cil/ |
| 17:18.09 | prpplague | landley: but i was curious if you had done anything with that kind of stuff |
| 17:19.14 | landley | Um, I generally just do it by hand? |
| 17:20.03 | landley | 50% of the time concatenating them should work, since the #includes have guards. |
| 17:20.38 | landley | A cleaner way would be some sed script or something that collates the #includes at the start and works out what to do about boilerplate comments at the start (although functionally you can just ignore comments). |
| 17:21.11 | landley | The actual conflicts would most likely be static functions and globals, and they don't really conflict much in practice. |
| 17:21.48 | landley | Oh, and #defines getting redefined without an appropriate #undef, but again if it's in headers they should have guards already. |
| 17:22.22 | landley | There's a theoretical risk with moving headers to the top of the file that they #define something that would screw _up_ code above that which hadn't previously seen that thing, but the standard headers should essentially never do this. |
| 17:22.32 | landley | prpplague: Did that answer your question? |
| 17:24.34 | prpplague | reads |
| 17:25.15 | prpplague | landley: yea that basically covers what i had figured out |
| 17:25.22 | prpplague | landley: just wanted a sanity check |
| 17:26.39 | landley | I actually bumped into this trying to do the build-at-once thing on toybox by creating one big file instead of going gcc *.c |
| 17:26.53 | landley | I decided that I _could_ do it, but it was way too much like work. |
| 17:27.14 | landley | And then more recently I found out that gcc *.c even with --build-at-once mode sends each file to the assembler separately, because the gcc developers are crazy. |
| 17:27.32 | landley | So I may revisit it at some point, but for right now getting the command list filled out comes first. |
| 17:29.10 | prpplague | landley: yea i have come to the same conclusion |
| 17:29.26 | prpplague | landley: the CIL toolset is pretty interesting though |
| 17:29.35 | prpplague | landley: let me do a pastebin |
| 17:31.50 | prpplague | landley: simple hello world - http://pastebin.pandaboard.org/index.php/view/76886860 |
| 17:32.15 | prpplague | landley: then run through cil it generates - http://pastebin.pandaboard.org/index.php/view/48981995 |
| 17:34.17 | landley | Why? |
| 17:34.33 | landley | I mean... I sort of see what it's doing, but... why? |
| 17:35.19 | landley | This is a variant of that stanford checker thing, or sparse? MOdern lint? |
| 17:35.27 | prpplague | landley: i was experimenting with methods of "exporting" code from one type of dev environment to another |
| 17:35.56 | prpplague | landley: just an experiment |
| 17:44.36 | calculus | prpplague: if only you can get at gcc's complete AST and shove it somewhere else |
| 17:46.11 | *** part/#edev landley (~landley@140.242.26.2) |
| 17:56.44 | prpplague | calculus: yea i figured it would be an interesting experiment |
