2012-10-06tcg: remove obsolete jmp opAurelien Jarno
The TCG jmp operation doesn't really make sense in the QEMU context, it is unused, it is not implemented by some targets, and it is wrongly implemented by some others. This patch simply removes it.

2012-09-27tci: Fix for AREG0 free modeStefan Weil
Support for helper functions with 5 arguments was missing in the code generator and in the interpreter. There is no need to pass the constant TCG_AREG0 from the code generator to the interpreter. Remove that code for the INDEX_op_qemu_st* opcodes. Signed-off-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2012-09-15Remove unused CONFIG_TCG_PASS_AREG0 and dead codeBlue Swirl
Now that CONFIG_TCG_PASS_AREG0 is enabled for all targets, remove dead code and support for !CONFIG_TCG_PASS_AREG0 case. Remove dyngen-exec.h and all references to it. Although included by hw/spapr_hcall.c, it does not seem to use it. Remove unused HELPER_CFLAGS. Signed-off-by: Blue Swirl <blauwirbel@gmail.com> Reviewed-by: Richard Henderson <rth@twiddle.net>
2012-06-22tci: Support INDEX_op_bswap64_i64Stefan Weil
Running the Windows 7 (64 bit) boot process needs INDEX_op_bswap64_i64. It was already implemented, but untested. Remove the TODO() statement. Signed-off-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
2012-05-08tci: Fix wrong macro name for debug codeStefan Weil
Code which is compiled with CONFIG_TCG_DEBUG (set by configure option --enable-debug-tcg) should not disable the assert macro by defining NDEBUG. With the wrong macro name CONFIG_TCG_DEBUG, all assertions in tci.c were completely useless because NDEBUG was always defined.

2012-04-21tci: GETPC() macro must return an uintptr_tStefan Weil
Change the data type of tci_tb_ptr, so GETPC() returns an uintptr_t now (like for all other TCG targets). This completes commit 2050396801ca0c8359364d61eaadece951006057 and fixes builds with TCI.

2012-04-07tci: Support targets with CONFIG_TCG_PASS_AREG0 (fix broken build)Stefan Weil
Builds with --enable-tcg-interpreter failed because more and more targets (currently alpha and sparc) replaced the global env in AREG0 by function parameters. Convert the TCG interpreter to use the new helper functions and add defines for those targets which still use AREG0.

2012-03-17w64: Fix data type of next_tb and tcg_qemu_tb_execStefan Weil
next_tb is the numeric value of a tcg target (= QEMU host) address. Using tcg_target_ulong instead of unsigned long shows this and makes the code portable for hosts with an unusual size of long (w64). The type cast '(long)(next_tb & ~3)' was not needed (casting unsigned long to long does not change the bits, and nor does casting long to pointer for most (= all non w64) hosts. It is removed here. Macro or function tcg_qemu_tb_exec is used to set next_tb. The function also returns next_tb. Therefore tcg_qemu_tb_exec must return a tcg_target_ulong.
