* cchecklink continues when sections overlapvarobert2012-05-243-62/+77
| | | | | | | cchecklink now reports overlapping sections but keeps analyzing. Error messages have also been made clearer. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1901 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

* cchecklink now reads segments instead of sectionsvarobert2012-05-108-285/+354
| | | | | | | | | | | | | cchecklink is now using program header information to figure out the initial address space of the program, rather than the information in the parent section of each symbol. This decouples the resolution of symbols from inaccurate section information, reflecting more the actual program loading. Additionally, a -relaxed option has been added to deal with some strange ELFs, for instance when symbols data is dynamically bootstrapped from another place by boot code different than the program loader. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1893 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

* Added small data area support to checklinkvarobert2012-04-203-58/+201
| | | | | | | | Accesses to small data areas are dynamically resolved by constructing a mapping from registers to virtual addresses they are supposed to point to. This mapping is reported. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1880 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* New section mapping checks and symbol data lookupvarobert2012-04-134-57/+118
| | | | | | | | | Section mapping is now discovered on-the-fly, and linker script remappings are reported as warnings at the end. Symbol data lookup is now able to gracefully fail if the symbol's virtual address is not within the range of its parent section's virtual address space. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1878 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

* Faster ndxes_of_sym_namevarobert2012-04-125-26/+51
| | | | | | | | | ndxes_of_sym_name used to have an O(s^2) complexity where s was the number of symbols in the ELF file. It has now been reduced to an O(s*ln(s)) by pre-computing the sets of symbols corresponding to each normalized symbol name. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1875 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
