2016-05-19cpu: move exec-all.h inclusion out of cpu.hPaolo Bonzini
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 Maydell
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 Henderson
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 Henderson
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 Maydell
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 Henderson
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 Henderson
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 Henderson
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 Henderson
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>
