- * the places in the code that need to be updated when making changes --
- * if you replace "OP_UNUSED_2D" and neglect to update a switch statement,
- * the compiler will complain about an unknown value.
- *
- * Opcode definitions and attributes:
- * - update the OpCode enum below
- * - update the "goto table" definition macro, DEFINE_GOTO_TABLE(), below
- * - update the instruction info table generators and (if you changed an
- * instruction format) instruction decoder in InstrUtils.c
- * - update the instruction format list in InstrUtils.h, if necessary
- * - update the parallel definitions in the class dalvik.bytecode.Opcodes
- *
- * Interpreter:
- * - implement/update the instruction in C in mterp/c/...
- * - verify new code by running with "dalvik.vm.execution-mode =
- * int:portable" or "-Xint:portable"
- * - implement/update the instruction in ARM in mterp/armv5/...
- * - verify by enabling ARM handler for that instruction in mterp config
- * and running int:fast as above
- * - repeat for other platforms (x86, ...)
- * (see notes in mterp/ReadMe.txt for rebuilding instructions)
- *
- * Verifier / optimizer:
- * - update some stuff in analysis/DexOptimize.c, analysis/DexVerify.c,
- * and/or analysis/CodeVerify.c as needed
- * - verify by running with verifier enabled (it's on by default)
- *
- * Tools:
- * - update the OpCodeNames table in dexdump/OpCodeNames.c
- * - update dexdump/DexDump.c if an instruction format has changed
- *
- * Note: The Dalvik VM tests (in the tests subdirectory) provide a convenient
- * way to test most of the above without doing any rebuilds. In particular,

-SHA-1 in C

-100% Public Domain
-
------------------
-Modified 7/98
-By James H. Brown <jbrown@burgoyne.com>
-Still 100% Public Domain
-
-bit machines
-Routine SHA1Update changed from
- void SHA1Update(SHA1_CTX* context, unsigned char* data,
- unsigned int len)
-to
- void SHA1Update(SHA1_CTX* context, unsigned char* data,
- unsigned long len)
-
-The 'len' parameter was declared an int which works fine on 32
-bit machines. However, on 16 bit machines an int is too small
-for the shifts being done against it. This caused the hash
-function to generate incorrect values if len was greater than
-8191 (8K - 1) due to the 'len << 3' on line 3 of SHA1Update().
-
-Since the file IO in main() reads 16K at a time, any file 8K or
-larger would be guaranteed to generate the wrong hash (e.g.
-Test Vector #3, a million "a"s).
-
-I also changed the declaration of variables i & j in SHA1Update
-to unsigned long from unsigned int for the same reason.
-
-These changes should make no difference to any 32 bit
-implementations since an int and a long are the same size in
-those environments.
-
---
-I also corrected a few compiler warnings generated by Borland
-C.
-1. Added #include <process.h> for exit() prototype
-2. Removed unused variable 'j' in SHA1Final
-3. Changed exit(0) to return(0) at end of main.
-
-ALL changes I made can be located by searching for comments
-containing 'JHB'
-
------------------
-Modified 13 August 2000
-By Michael Paul Johnson <mpj@cryptography.org>
-Still 100% Public Domain
-
-Changed command line syntax, added feature to automatically
-check files against their previous SHA-1 check values, kind of
-like md5sum does. Added functions hexval, verifyfile,
-and sha1file. Rewrote main().
