Hi ALL... I am new to SAMBA, when i am trying to compile SAMBA by using make, It is just waiting and doing nothing. make Using FLAGS = -O -I./popt -Iinclude -I/opt2/samba/samba-3.0.2a/source/include -I/opt2/samba/samba-3.0.2a/source/ubiqx -I/opt2/samba/samba-3.0.2a/source/smbwrapper -I. -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/opt2/samba/samba-3.0.2a/source LIBS = -lsendfile -lsec -lgen -lresolv -lsocket -lnsl -ldl LDSHFLAGS = -G L...

It passes the LLVM regression tests and helps to reduce the runtime of 'opt -basicaa -licm out.opt.ll’ from 130ms to 67ms and the runtime of 'opt -basicaa -licm out.opt2.ll’ from 117ms to 62ms (out.opt.ll and out.opt2.ll can be found on the following link https://llvm.org/bugs/show_bug.cgi?id=23077).

Hi, trying to install a package containing C code and requiring non-default configure argument settings the incantation (this has worked for R <= 2.8.1 on the same architectures) R CMD INSTALL --configure-args="--with-opt1 --with-opt2" packname does always result in a warning Warning: unknown option '--with-opt2' and consequently the option is ignored. Reverting the order of options results in the now last option to be ignored. Alternative quoting has not provided a solution. Using R CMD INSTALL --configure-args...

Hi Zide, I think I found the right way to reach my goal. I used the following command: clang -O3 -Xclang -disable-llvm-optzns main.c -S -emit-llvm -o main.ll to generate an IR file enriched by all the metadata that otherwise wouldn't be generated with -O0. Moreover, -disable-llvm-optzns flag ensures that none of the optimization passes has been applied yet to the IR. In this way, I can

PIC16 now has clang and llc based system to generate native assembly. We then use our native assembler (gpasm) and the native linker (mplink) to generate the final executable. How can I integrate these things with the driver llvmc to have gcc like user experience? Note that we also want to run llvm-ld in order to perform the LTOs in case of multiple files. - Sanjiv

Buenas a todos, acá estoy yo de nuevo con problemas de loops. Tengo el siguiente problema: un vector de datos (y) y una serie de efectos. El loop lo que intenta es evaluar el R² de modelos incrementando por vuelta una variable efecto. Seria algo así: for(i in 1:x) { modelo=lm(y~efectos[,1:i]) ... codigo para guardar R² y otros por cada vuelta... } apply() puede ir columna a columna pero no
