| Any Android specific modifications to upstream libjpeg-turbo (1.4.2) should |
| be listed here: |
| |
| (1) jconfig.h and jconfigint.h |
| |
| These are included upstream as jconfig.h.in and jconfigint.h.in. |
| We have the option autogenerate these platform/version specific files (using |
| the libjpeg-turbo build system) or to manually create them. |
| |
| Autogenerating these files on linux gets us most of the way, but we've needed |
| to add some multi-platform flexibility to the INLINE and SIZEOF_SIZE_T macros. |
| |
| (2) Partial decoding optimizations |
| |
| These have been cherry picked from upstream and will be included in the 1.5 |
| release. The cherry picked commits are: |

| |
| (3) simd/jsimdext.inc |
| |
| The modification enables us to compile x86 SIMD. |
| |
| The original code was: |
| %define EXTN(name) _ %+ name |
| The new code is: |
| %define EXTN(name) name |
| |
| It is unclear why the unmodified code from upstream appends an underscore |
| to name. Before removing the underscore, the code failed to link because |
| the function names in the SIMD code did not match the callers (because of |
| the extra underscore). |
