|
* src/malloc.cxx (free):
|
| 4 |
|
|
* src/kapi.cxx (cyg_mempool_var_free, cyg_mempool_fix_free): Fix
|
| 5 |
|
|
compiler warnings about variables that are set but never
|

* src/heapgen.tcl (tcl_path): use the makefile's HOST instead of

| 11 |
|
|
tcl_platform() to figure out host details.

|
|
|
| 15 |
|
|
* src/malloc.cxx (cyg_memalloc_heap_reinit): Added this function
|
| 16 |
|
|
to reinitialize the heap to a new arena. This should be done
|
| 17 |
|
|
during system startup and is present mainly for the use of
|
| 18 |
|
|
RedBoot.
|
| 19 |
|
|
Permit configurations with multi-region heaps to build.
|
| 20 |
|
|
[Imported from eCosPro sources, mainly to support use of
|
| 21 |
|
|
filesystems in RedBoot].

|
|
|
| 31 |
|
|
* cdl/memalloc.cdl: Invoke tclsh explicitly to avoid the need for
|
| 32 |
|
|
execute permission on heapgen.tcl.
|
| 33 |
|
|
|
| 34 |
|
|
2009-01-08 John Dallaway
|
| 35 |
|
|
|
| 36 |
|
|
* src/heapgen.tcl: Specify script interpreter via /usr/bin/env.
|
| 37 |
|
|
* cdl/memalloc.cdl: Simplify heaps.cxx make rule - cygtclsh80 is
|
| 38 |
|
|
no-longer supported.

|
|
* src/dlmalloc.cxx (MALLOC_COPY): Reinstate fix of 2008-01-06
|
| 43 |
|
|
(reverting change of 2008-11-03).
|
| 44 |
|
|
* cdl/memalloc.cdl (CYGIMP_MEMALLOC_ALLOCATOR_DLMALLOC_USE_MEMCPY):
|
| 45 |
|
|
Make explicit dependency on isoinfra functionality block which
|
| 46 |
|
|
includes memmove(), and set default_value accordingly.
|
| 47 |

2008-11-03 Nick Garnett
|
| 49 |
|
|
|
| 50 |
|
|
* src/dlmalloc.cxx (MALLOC_COPY): Replace memmove() with memcpy().
|
| 51 |
|
|
|
| 52 |
|
|
* include/dlmallocimpl.hxx (class Cyg_Mempool_dlmalloc_Implementation):
|
| 53 |

|
| 56 |
|
|
|
| 57 |
|
|
* src/dlmalloc.cxx (MALLOC_COPY):
|
| 58 |
|
|
* cdl/memalloc.cdl: Use memmove instead of memcpy which can go
|
| 59 |
|
|
wrong in realloc() when the new and old block overlaps.
|
| 60 |
|
|
CYGIMP_MEMALLOC_ALLOCATOR_DLMALLOC_USE_MEMCPY has been retained
|
| 61 |
|
|
instead of being renamed to ..._MEMMOVE to help backward
|
| 62 |
|
|
compatibility with older configurations. Thanks to Oyvind Harboe
|
| 63 |
|
|
and Dave Lawrence.

|
2007-11-05 Oyvind Harboe
|
| 66 |
|
|
|
| 67 |
|
|
* cdl/memalloc.cdl: Added option CYGBLD_MEMALLOC_MALLOC_EXTERNAL_JOIN_H
|
| 68 |
|
|
to let applications implement a way to pick the pool to allocate memory
|
| 69 |
|
|
from based on an application specific heuristic.
|
| 70 |
|
|
* src/malloc.cxx: Use it.
|

2007-10-24 Jonathan Larmour
|
| 74 |
|
|
|
| 75 |
|
|
* src/malloc.cxx: Init priority for pool initialization is now
|
| 76 |
|
|
CYG_INIT_MEMALLOC instead of before CYG_INIT_LIBC
|
| 77 |
|
|
* src/heapgen.tcl: Ditto.

2006-05-17 Andrew Lunn
|
| 80 |
|
|
|
| 81 |
|
|
* doc/memalloc.sgml: Fix parameters for calloc. Reported by
|
| 82 |
|
|
Andy Jackson.
|
| 83 |
|
|
|
| 84 |
|
|
2005-09-30 Alexander Neundorf
|
| 85 |
|
|
|
| 86 |
|
|
* doc/memalloc.sgml: two minor fixes
|
| 87 |
|
|
|
| 88 |
|
|
2005-07-30 Andrew Lunn
|
| 89 |
|
|
|
| 90 |
|
|
* tests/heaptest.c (test_pat): Casts to prevent compiler warnings.
|
| 91 |
|
|
* tests/testaux.hxx: new cannot be both global and static.
|
| 92 |
|
|
|
| 93 |
|
|
2005-07-22 Andrew Lunn
|
| 94 |
|
|
|
| 95 |
|
|
* cdl/memalloc.cdl: Use the CXXFLAGS for the native compiler to
|
| 96 |
|
|
avoid passing it flags only valid for C.
|
| 97 |
|
|
|
| 98 |
|
|
2005-03-27 Andrew Lunn
|
| 99 |
|

2004-10-04 Oyvind Harboe
|
| 106 |
|
|
|
| 107 |
|
|
* src/dlmalloc.cxx (resize_alloc): No longer invoke
|
| 108 |
|
|
cyg_memalloc_alloc_fail() on failure to resize. It is not an out
|
| 109 |
|
|
of memory condition, it just means the current memory allocation
|
| 110 |
|
|
could not be expanded. realloc() will try allocating a completely
|
| 111 |
|
|
new block of memory and only if that fails do we have an out of
|
| 112 |
|
|
memory condition.
|
| 113 |
|
|
|
| 114 |
|
|
2004-10-01 Oyvind Harboe
|
| 115 |
|
|
|
| 116 |
|
|
* heapgen.tcl: place the CYGBLD_ATTRIB_INIT_PRI such that it
|
| 117 |
|
|
compiles for gcc 3.4.2 which is more picky about its placement.
|
| 118 |
|
|
|
| 119 |
|
|
2004-06-24 Oyvind Harboe
|
| 120 |
|
|
|
| 121 |
|
|
* Added cyg_memalloc_alloc_fail() fn which is invoked before
|
| 122 |
|
|
return NULL from failed allocations. Useful breakpoint site.
|
| 123 |
|
|
Andrew Lunn wrote some of the code and pointed out various
|
| 124 |
|
|
wrinkles to be ironed out.

|
|
2002-01-30 Bart Veer
|
| 166 |
|
|
|
| 167 |
|
|
* tests/malloc4.cxx:
|
| 168 |

2001-10-17 Jesper Skov

|
| 246 |
|
|
|
| 247 |
|
|
2001-06-18 Jonathan Larmour
|
| 248 |
|
|

|
2001-05-02 Hugo Tyson
|
| 266 |
|
|
|
| 267 |
|
|
* src/dlmalloc.cxx (Cyg_Mempool_dlmalloc_Implementation): Fix
|
| 268 |
|
|
previous change; "top" is a pseudo variable via a NULL pointer if
|
| 269 |
|
|
the heap is not initialized, so you can't use it as a flag for "no
|
| 270 |
|
|
mem here"; and a typo, the comparison was reversed. The two hid
|
| 271 |
|
|
each other, so the check for "no mem here" usually said "OK".
|
| 272 |
|
|
|
| 273 |
|
|
2001-05-01 Jonathan Larmour

2001-04-12 Hugo Tyson
|
| 281 |
|
|
|
| 282 |
|

|
|
This only applies if you configure multiple heaps.

|
* cdl/memalloc.cdl: Invoke heapgen.tcl with build directory
|
| 307 |
|
|
surrounded by quotes (and do so in a portable way).
|
| 308 |
|
|
|
| 309 |
|
|
* src/heapgen.tcl: recurse back in on cygwin with correct quoting
|
| 310 |
|

|
|
compatible way.

New option.

|
|
* tests/realloc.c (main): Use reasonable factor when making too
|
| 323 |

large realloc (targets with 64MB would cause an overflow).

var in each thread.

|
|
use of CYG_LABEL_DEFN macro
|
| 396 |
|
|
|
| 397 |

* CYGPKG_MEMALLOC:
|
| 408 |
|
|
|
| 409 |
|
|
Created as new package, merging existing memory allocator related stuff
|
| 410 |
|
|
from the kernel and libc. Many bug fixes to existing stuff, as
|
| 411 |
|
|
well as performance improvements, and extra features such as
|
| 412 |
|
|
a port of dlmalloc, and the ability to support multiple disjoint
|
| 413 |
|
|
heaps, possibly with run-time configurable size.
|
| 414 |
|
|
There's even a bit of documentation, and some new tests
|
| 415 |
