1 Any Android specific modifications to upstream libjpeg-turbo (1.4.2) should 2 be listed here: 3 4 (1) jconfig.h and jconfigint.h 5 6 These are included upstream as jconfig.h.in and jconfigint.h.in. 7 We have the option autogenerate these platform/version specific files (using 8 the libjpeg-turbo build system) or to manually create them. 9 10 Autogenerating these files on linux gets us most of the way, but we've needed 11 to add some multi-platform flexibility to the INLINE and SIZEOF_SIZE_T macros. 12 13 (2) Partial decoding optimizations 14 15 These have been cherry picked from upstream and will be included in the 1.5 16 release. 17 18 (3) Security fix 19 20 Cherry picked from upstream to address b/27494207. 21 22 (4) simd/jsimdext.inc 23 24 The modification enables us to compile x86 SIMD. 25 26 The original code was: 27 %define EXTN(name) _ %+ name 28 The new code is: 29 %define EXTN(name) name 30 31 It is unclear why the unmodified code from upstream appends an underscore 32 to name. Before removing the underscore, the code failed to link because 33 the function names in the SIMD code did not match the callers (because of 34 the extra underscore). 35
