2012-10-17tcg/arm: Implement movcond_i32Peter Maydell1-1/+1
Implement movcond_i32 for ARM, as the sequence mov dst, v2 (implicitly done by the tcg common code) cmp c1, c2 movCC dst, v1 Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2012-10-12tcg: Remove TCG_TARGET_HAS_GUEST_BASE definePeter Maydell1-2/+0
GUEST_BASE support is now supported by all TCG backends, and is now mandatory. Drop the now-pointless TCG_TARGET_HAS_GUEST_BASE define (set by every backend) and the error if it is unset.

Implemented with setcond if the target does not provide the optional opcode. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2012-09-15Remove unused CONFIG_TCG_PASS_AREG0 and dead codeBlue Swirl1-1/+0
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>
2012-03-03w64: Change data type of parameters for flush_icache_rangeStefan Weil1-1/+2
The TCG targets i386 and tci needed a change of the function prototype for w64. This change is currently not needed for the other TCG targets, but it can be applied to avoid code differences.

2012-01-10tcg/arm: Use r6 as TCG_AREG0 to avoid clash with Thumb framepointerPeter Maydell1-1/+1
On ARM, in Thumb mode r7 is used for the framepointer; this meant that we would fail to compile in debug mode because we were using r7 for TCG_AREG0. Shift to r6 instead to avoid this clash. (Bug reported as LP:870990.) Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Andrzej Zaborowski <andrew.zaborowski@intel.com>
2011-11-14tcg: Standardize on TCGReg as the enum for hard registersRichard Henderson1-2/+2
Most targets did not name the enum; tci used TCGRegister. Signed-off-by: Richard Henderson <rth@twiddle.net> Reviewed-by: Andreas Färber <afaerber@suse.de> Reviewed-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2011-10-01tcg: Don't declare TCG_TARGET_REG_BITS in tcg-target.hStefan Weil1-1/+0
It is now declared for all tcg targets in tcg.h, so the tcg target specific declarations are redundant. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-08-21tcg: Always define all of the TCGOpcode enum members.Richard Henderson1-14/+16
By always defining these symbols, we can eliminate a lot of ifdefs. To allow this to be checked reliably, the semantics of the TCG_TARGET_HAS_* macros must be changed from def/undef to true/false. This allows even more ifdefs to be removed, converting them into C if statements. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-04-19tcg/arm: add bswap opsAurelien Jarno1-2/+2
Add an bswap16 and bswap32 ops, either using the rev and rev16 instructions on ARMv6+ or shifts and logical operations on previous ARM versions. In both cases the result use less instructions than the pure TCG version. These ops are also needed by the qemu_ld/st functions. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-04-19tcg/arm: add ext16u opAurelien Jarno1-2/+2
Add an ext16u op, either using the uxth instruction on ARMv6+ or two shifts on previous ARM versions. In both cases the result use the same number or less instructions than the pure TCG version. Also move all sign extension code to separate functions, so that they can be reused in other parts of the code. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-04-19tcg/arm: explicitely list clobbered/reserved regsAurelien Jarno1-1/+2
Instead of writing very compact code, declare all registers that are clobbered or reserved one by one. This makes the code easier to read. Also declare all the 16 registers to TCG, and mark pc as reserved. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-03-14tcg: add div/rem 32-bit helpersAurelien Jarno1-0/+1
Some targets like ARM would benefit to use 32-bit helpers for div/rem/divu/remu. Create a #define for div2 so that targets can select between div, div2 and helper implementation. Use the helper version if none of the #define are present. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
