Documentating the removal of -fshared-data

2006-05-29 Thread Martin Michlmayr
The -fshared-data option has been removed in GCC 4.2, but as far as I can tell this is not documented anywhere. Would it be possible to mention this at http://gcc.gnu.org/gcc-4.2/changes.html, and possibly in a section of the GCC manual? 2006-02-21 Richard Sandiford <[EMAIL PROTECTED]>

Freeing memory for basic-blocks and edges

2006-05-29 Thread sean yang
I am looking for code that corresponds to freeing memory for BBs and Edges. For example, I know to allocate a chunk of memory to hold BB information is done by "ggc_alloc_cleared()". But after a function analysis/optimization is done, the memory should be freed. I tried to read code in rest_o

typeof and const qualifier

2006-05-29 Thread Roman Zippel
Hi, gcc 4.1 changed the typeof behaviour and now includes the type const qualifier, which unfortunately breaks existing code. The example below is simplified example from the Linux kernel (i386 was "fixed", but that's not the only arch). The first get_user() produces nice code with 4.0 and ear
