2016-05-19cpu: move exec-all.h inclusion out of cpu.hPaolo Bonzini1-0/+1
exec-all.h contains TCG-specific definitions. It is not needed outside TCG-specific files such as translate.c, exec.c or *helper.c. One generic function had snuck into include/exec/exec-all.h; move it to include/qom/cpu.h. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-01-29alpha: Clean up includesPeter Maydell1-0/+1
Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1453832250-766-12-git-send-email-peter.maydell@linaro.org
2015-08-18target-alpha: Special case cmpbge with zeroRichard Henderson1-0/+14
Knowing the comparator is zero leads to a simpler operation. Signed-off-by: Richard Henderson <rth@twiddle.net>
2015-08-17target-alpha: Rewrite helper_cmpbge using bit testsRichard Henderson1-13/+26
Not quite as good as using a proper host vector compare, but certainly better than a loop. Signed-off-by: Richard Henderson <rth@twiddle.net>
2015-05-22Revert "target-alpha: Add vector implementation for CMPBGE"Peter Maydell1-37/+0
This reverts commit 32ad48abd74a997220b841e4e913edeb267aa362. Unfortunately the SSE2 code here fails to compile on some versions of gcc: target-alpha/int_helper.c:77:24: error: invalid operands to binary >= (have '__vector(16) unsigned char' and '__vector(16) unsigned char') Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2015-05-21target-alpha: Add vector implementation for CMPBGERichard Henderson1-0/+37
While conditionalized on SSE2, it's a "portable" gcc generic vector implementation, which could be enabled on other hosts. Signed-off-by: Richard Henderson <rth@twiddle.net>
2015-05-21target-alpha: Rewrite helper_zapnotRichard Henderson1-18/+12
This form produces significantly smaller code on x86_64. Signed-off-by: Richard Henderson <rth@twiddle.net>
2015-05-18target-alpha: Fix integer overflow checking insnsRichard Henderson1-57/+2
We need to write the result to the destination register before raising any exception. Thus inline the code for each insn, and check for any exception after we're done. Reported-by: Al Viro <viro@ZenIV.linux.org.uk> Signed-off-by: Richard Henderson <rth@twiddle.net>
2014-05-28tcg: Invert the inclusion of helper.hRichard Henderson1-1/+1
Rather than include helper.h with N values of GEN_HELPER, include a secondary file that sets up the macros to include helper.h. This minimizes the files that must be rebuilt when changing the macros for file N. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <rth@twiddle.net>
