I thought this conversation was worth saving. DannyB who did wonderful things with GCC's use of bugzilla has offered the same capability to LLVM. Thanks, Danny! <DannyB> sabre: BTW, if you need any of the bugzilla fun i have implemented for gcc, let me know [22:47] <sabre> Cool, what kinds of things do you have?

Hi David, It looks like you added the PWD= magic to Makefile.spec. It is preventing me from running bugpoint on the desktop, with errors like this: /Users/sabre/llvm/projects/llvm-test/External/SPEC/Sandbox.sh bugpoint- train Output/176.gcc.bugpoint-opt /Users/sabre/cvs/benchmarks/ speccpu2000/benchspec/CINT2000/176.gcc/data/train/input/ \ PWD=/Volumes/Data/Users/sabre/llvm/projects/llvm-test/External/ SPEC/CINT2000/176.gcc /Users/sabre/llvm/Debug/...

This certainly doesn't occur in gcc mainline. In fact, I improved the error message, and added a error test to gcc just yesterday.

Yep, clang reports: t.c:4:12: error: read-only variable is not assignable arr[0] = 1; ~~~~~~ ^ 1 diagnostic generated. so this is specific to llvm-gcc somehow. -Chris > On 8/9/07, Chris Lattner <sabre at nondot.org> wrote: >> On Wed, 8 Aug 2007, Nikhil A.

I commented this line and it is compiling now: extern void *malloc ARGS((unsigned)); I hope that will not cause a different kind of problem. What it is zalloc used for?

How hard would it be to compile this pass and add it to the passes that opt can run? Is this something I should be able to do relatively quickly? What was the name of the file(s) that implemented the pass?

Hi all, For anyone interested, I posted two new ideas for changes to the LLVM IR. The first is basically a cleanup, the second is a major new feature: Eliminating the 'Void' Type: http://nondot.org/sabre/LLVMNotes/EliminatingVoid.txt Aggregates as First Class Values: http://nondot.org/sabre/LLVMNotes/FirstClassAggregates.txt Thanks to Dan Gohman for convincing me that aggregates as first class values is really possible, I think it is a great idea. -Chris

...ode the patterns for each instruction in the .td files, which are parsed by the tablegen tool. Tablegen then parses these files and emits various chunks of the code generator. It would emit the instruction selector from the patterns in the .td file. -Chris > On 4/25/05, Chris Lattner <sabre at nondot.org> wrote: >> On Mon, 25 Apr 2005, Tzu-Chien Chiu wrote: >>> http://portal.acm.org/citation.cfm?id=75700 >> >> Oh, tWig. :) Yes, tree pattern matching is exactly the direction we are >> heading.

...tion in the .td files, then build use an optimal code generator generator to emit the matching code. This processes of increased automation has been happening slowly over the years, but we've made good progress.

I think, we must move function arguments lowering from frontend to LLVM core. This lowering is generating machine dependent bytecode.
