2011-07-30	Do constant folding for unary operations.	Kirill Batuzov	1	-0/+59
	Perform constant folding for NOT and EXT{8,16,32}{S,U} operations. Signed-off-by: Kirill Batuzov <batuzovk@ispras.ru> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-07-30	Do constant folding for shift operations.	Kirill Batuzov	1	-0/+72
	Perform constant forlding for SHR, SHL, SAR, ROTR, ROTL operations. Signed-off-by: Kirill Batuzov <batuzovk@ispras.ru> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-07-30	Do constant folding for boolean operations.	Kirill Batuzov	1	-0/+37
	Perform constant folding for AND, OR, XOR operations. Signed-off-by: Kirill Batuzov <batuzovk@ispras.ru> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-07-30	Do constant folding for basic arithmetic operations.	Kirill Batuzov	1	-0/+125
	Perform actual constant folding for ADD, SUB and MUL operations. Signed-off-by: Kirill Batuzov <batuzovk@ispras.ru> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-07-30	Add copy and constant propagation.	Kirill Batuzov	1	-2/+180
	Make tcg_constant_folding do copy and constant propagation. It is a preparational work before actual constant folding. Signed-off-by: Kirill Batuzov <batuzovk@ispras.ru> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-07-30	Add TCG optimizations stub	Kirill Batuzov	1	-0/+97
	Added file tcg/optimize.c to hold TCG optimizations. Function tcg_optimize is called from tcg_gen_code_common. It calls other functions performing specific optimizations. Stub for constant folding was added. Signed-off-by: Kirill Batuzov <batuzovk@ispras.ru> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
