1053 * smp/upc_vm.c (__upc_vm_alloc): Return an error if no
1054 more virtual pages can be allocated.
1055 (__upc_vm_alloc): Abort if initial number of VM pages cannot

1070 Define UPCFLAGS so that it is available in the Makefile,
1071 and assign CFLAGS as its default value.
1073 * configure.ac (UPCFLAGS): Default to CFLAGS if not set.
1074 (UPCFLAGS): Make it an AC_SUBST() so that it can
1075 be referenced in the Makefile.
1076 * Makefile.am (AM_UPCFLAGS): Make sure that it is update
1077 the same as AM_CFLAGS.
1078 * configure, Makefile.in: Re-generate.
1080 2011-06-06 Nenad Vukicevic <nenad@intrepid.com>
1082 * smp/upc_config.h: Change default scheduling policy.
1083 Allow the kernel to schedule UPC threads on its own.

1108 * configure.ac (upc_crtstuff_mak): New AC_SUBST variable.
1109 * configure.tgt (upc_crtstuff_mak): Find upc-crtstuff.mak
1111 * Makefile.am (upc_crtstuff_mak): Set make variable to value

1125 * configure.tgt: Move linker switches into libupc.spec.
1127 2011-03-20 Gary Funck <gary@intrepid.com>
1129 Place error message strings directly into the calls to
1130 __upc_fatal(), rather than listing them separately
1131 as #define's. The intent of this change is to make
1132 it easier to internationalize the message text
1133 using standard tools.
1135 * include/gcc-upc-lib.in: Remove include of lib_config_msgs
1138 * smp/upc_config.h: Remove #define's used to provide named
1139 references to error messages.
1141 * smp/upc_lock.c, smp/upc_numa.c, smp/upc_access.c,
1142 smp/upc_vm.c, smp/upc_main.c, smp/upc_alloc.upc,
1143 smp/upc_sysdep.c, smp/upc_affinity.c, smp/upc_addr.c,
1144 smp/upc_mem.h, smp/upc_barrier.c: Replace named references
1145 with actual error message text strings.
1147 2011-03-20 Gary Funck <gary@intrepid.com>
1149 Move UPC start files, end files, and linker specs.
1150 into libupc. This reduces the impact on common GCC
1151 configuration files, and ensures that these UPC-specific
1152 components are only built when the UPC language dialect is built.
1154 * upc-crtstuff.c: New file. Moved from gcc/upc/upc-crtstuff.c.
1156 * config/darwin/upc-crt-config.h: New file. Move defines for
1157 UPC-related section begins/ends from gcc/config/darwin.h to here.
1159 * config/default/upc-crt-config.h: New file. Move defines for
1160 UPC-related section begins/ends from gcc/config/upc-conf.h to here.
1162 * config/default/upc-crtstuff.mak: New file. Default makefile fragment for
1163 building the upc-crtbegin and upc-crtend object files.
1164 This logic was moved from libgcc/Makefile.in to here.
1166 * config.h.in: Regenerate with autoheader. Rename HAVE_GUM_DEBUG
1167 to GUPCR_HAVE_GUM_DEBUG. Add define for HAVE_UPC_LINK_SCRIPT.
1169 * configure.ac, configure: Include new configure.tgt script
1170 towards the end of the logic that configures the smp runtime.
1171 Define substitutions for 'config_path', 'XCFLAGS',
1172 'XLDFLAGS', 'link_upc_spec', 'upc_crtbegin_spec',
1173 'upc_crtend_spec', 'upc_crtstuff_objs'. Add LIBUPC_CRTSTUFF
1174 automake conditional. Fix copyright date in AM_TOP() comment.
1175 Define upc-crtbegin.spec libupc.spec upc-crtend.spec as
1176 autoconf generated config. files. Regenerate 'configure'.
1178 * configure.tgt: New. Target-specific configuration logic.
1179 Defines 'config_path', 'upc_crtstuff', 'upc_crtbegin_spec',
1180 'upc_crtend_spec', 'upc_crtstuff_objs' variables; these are used
1181 to control the build of the UPC-related begin/end files
1182 and associated target-specific compiler specification files.
1184 * libupc.spec.in, upc-crtbegin.spec.in, upc-crtend.spec.in: New.
1185 Define target-specific compiler specifications for linking
1186 and for inclusion of UPC-related start/end object files
1187 when a UPC program is linked. These files are used
1188 to create resulting .spec files that are included via
1189 GCC's link spec. when a UPC program is linked.
1191 * Makefile.am: Add rules to build and install upc-crtbegin.spec,
1192 libupc.spec, and upc-crtend.spec from there .in files.
1193 Add rules to build the UPC-specific start/end files if the
1194 automake conditional LIBUPC_CRTSTUFF is enabled.
1195 Fix references to make variables $(UPC_COLL_PREFIX_REDUCE_UPC)
1196 and $(UPC_COLL_REDUCE_UPC) in MAINTAINER_MODE block.
1198 * Makefile.in, testsuite/Makefile.in: Regenerate with automake.
1200 * smp/Make-defs, smp/Make-deps, smp/Make-rules: Remove.
1201 These Makefile fragments have not been used since libupc
1202 was re-worked to use automake (when the gupc branch
1203 was first checked in).
1205 * smp/upc_config.h: Move the defintions of GUPCR_INIT_ARRAY_START
1206 and GUPCR_INIT_ARRAY_END from smp/upc_main.c to here.
1208 * smp/upc_main.c: Rename HAVE_GUM_DEBUG to GUPCR_HAVE_GUM_DEBUG.
1209 Move the defintions of GUPCR_INIT_ARRAY_START and
1210 GUPCR_INIT_ARRAY_END to smp/upc_config.h.
1212 2011-02-22 Gary Funck <gary@intrepid.com>
1214 * include/gcc-upc.h (barrier, barrier_notify, barrier_wait,
1215 forall, fence): Remove #define's that renamed these deprecated
1216 UPC keywords into their equivalents in the current UPC
1217 language specification.

1237 2010-10-18 Gary Funck <gary@intrepid.com>
1239 * smp/upc_alloc.upc: upc_alloc.upc: remove pointer arithmetic on
1240 (shared void *) types.
1242 Now that GCC/UPC prohibits arithmetic on "(shared void *)" types,
1243 re-work the logic in upc_alloc.upc to avoid operating directly on
1244 "(shared void *)" type.
1246 2010-10-16 Gary Funck <gary@intrepid.com>

1252 * smp/: upc_access.c, upc_access.h, upc_accessg.c: Implement fixes
1253 for SGI/IRIX/MIPS port.
1255 The gcc/Makefile.in rules for install-plugin had to be re-written to
1256 break up a long list of header files that exceeded the command line
1257 limitation imposed by Irix.
1259 Access functions for TFmode types had to be implemented.
1260 Apparently, this is the mode used for the SGI/MIPS port to represent

1273 value on each thread.

1298 * smp/upc_main.c: Fix bug: Failure to initialize per-thread
1299 static variables that refer to shared addresses.
1301 The shared data initialization routine created by the compiler needs
1302 to be called on each threead, because in some cases it will
1303 initialize per thread data. At the moment, the compiler does not
1304 generate code that will differentiate between initialization code
1305 that should only occur on thread 0, so some additional work may get
1306 done. In the future, that aspect of initialization will be

1311 * include/gcc-upc-lib.in, include/upc.h, smp/upc_main.c:
1312 Fix bug: Nested upc_forall() semantics are not implemented
1314 The checkforall test in the Berkeley harness test suite indicated
1315 that GCC/UPC was not properly implementing nested upc_forall
1316 semantics. Nested upc_forall statements (both statically or
1317 dynamically nested) must implement their affinity clause as if it
1318 were "continue"; thus all steps in the loop must execute without
1319 regard for affinity. To implement these semantics a global depth
1320 counter, __upc_forall_depth, is maintained by the generated code
1321 that implements upc_forall.
