2015-10-09Various changes to JBig2 cache:David Lattimore
- Makes the cache be per-document - Keys the cache on ObjNum and stream offset instead of keying on a pointer to the data (which can result in false cache hits). - Makes it so the cache is only used for the globals stream. - Reenable the cache.

2015-06-11Kill FXSYS_mem{cpy,cmp,set.move}{32,8}.Tom Sepez
At one point in time, it may have made sense to indicate the expected alignment of the memory you're about to copy, but that was last century. The compiler will take care of it just fine. I stopped short of removing the FXSYS_ wrapper macros entirely. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1179693003.

2015-06-10Remove typdefs for pointer types in fx_system.h.Tom Sepez
This involves fixing some multiple variable per line declarations, as the textually-substituted "*" applies only to the first one. This involves moving some consts around following the substitution. This involves replacing some typedefs used as constructors with better code. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1171733003
2015-06-09Use stdint.h types throughout PDFium.Tom Sepez
It's redundant nowadays to provide our own equivalents, now that this is done for us by the system header. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1177483002
2015-06-04Move fx_safe_types.h to include/ directory.Tom Sepez
Small bit of OCD here, since this file is included cross-library (i.e. from fpdfsk), it can't be in src/. In other words, the following should be empty: grep -R 'include.*core/src/' fpdfsdk Fix some IWYU in it at the same time. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1147353006
2015-05-21Fix an endless loop in CJBig2_HuffmanTable::parseFromCodedBufferJUN FANG
This issue is trigged by the conversion from unsigned int to signed int. A large unsigned int is converted to int. It's represented as a negative int which is used in the condition of while later. BUG=482639 R=brucedawson@chromium.org Review URL: https://codereview.chromium.org/1146913003
