1 Any Android specific modifications to upstream libjpeg-turbo (1.5.1) 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) simd/jsimdext.inc 14 15 The modification enables us to compile x86 SIMD. 16 17 The original code was: 18 %define EXTN(name) _ %+ name 19 The new code is: 20 %define EXTN(name) name 21 22 It is unclear why the unmodified code from upstream appends an underscore 23 to name. Before removing the underscore, the code failed to link because 24 the function names in the SIMD code did not match the callers (because of 25 the extra underscore). 26 27 (3) jmemmgr.c 28 29 Fix broken build with NDK platforms < android-21 30 Cherry picked from upstream: 31 https://github.com/libjpeg-turbo/libjpeg-turbo/commit/dfefba77520ded5c5fd4864e76352a5f3eb23e74 32 33 (4) rdppm.c 34 Fix sign mismatch comparison warnings 35 Cherry picked from upstream: 36 https://github.com/libjpeg-turbo/libjpeg-turbo/commit/d22fd541bf9dd87889c25909e19a640a580bcad7 37
